Conventional and Holistic Treatment for Parkinson's Disease

🌿 HOLISTIC

💊 CONVENTIONAL

🌿

Holistic / Functional Approach

Complements medications. Exercise has among the strongest evidence of any non-drug intervention¹.

Exercise

Among the best-supported non-drug interventions for motor function, gait and quality of life¹. Aim for at least 2.5 hours a week, including options like boxing, dance or tai chi⁷.

Gut Health

Treat constipation, which also improves levodopa absorption¹².

Mitochondrial Support

CoQ10 and creatine were each tested in large randomized trials and neither improved outcomes²¹³; B12 is worth checking on levodopa²

Med Adjuncts

Improve levodopa absorption with proper timing; minimize side effects; preserve function

Full Holistic Approach Includes

Exercise, a priority: at least 2.5 hours a week, including aerobic work, boxing, tai chi, dance or cycling⁷. A randomized trial supported the feasibility of high-intensity treadmill exercise and its effect on motor symptoms¹.
Mediterranean / MIND diet, associated with lower risk and slower progression in observational studies². Olive oil, fatty fish, greens, nuts, berries.
Address constipation aggressively: fiber, fluids, magnesium, ground flax (amounts set with your prescriber). Untreated constipation reduces levodopa absorption¹².
Protein-redistribution diet, for those on levodopa who have motor fluctuations: take meds 30 to 60 min before meals; redistribute protein later in the day to maximize medication absorption
Coffee 2 to 3 cups/day, associated with lower Parkinson's risk in cohort studies, an association rather than a treatment²
Green tea, if you enjoy it; its polyphenols have been studied mainly in the laboratory
Microbiome support, diverse fiber, fermented foods. Avoid unnecessary antibiotics. Treat H. pylori if present (impairs levodopa absorption).
Sleep hygiene, critical for brain health. Address REM sleep behavior disorder.
Limit pesticide exposure: farm use of paraquat and rotenone has been linked with Parkinson's¹⁰
Speech therapy (intensive voice training), voice and swallowing preservation
Physical therapy (large-amplitude movement training): counters bradykinesia
Music therapy and rhythm cues, improve gait, reduce freezing
Tai chi, yoga, dance: improve balance, reduce falls, support brain plasticity
Address depression and anxiety, which are common; tell your care team⁶
Social engagement, fight isolation and apathy

✅ Exercise Is Medicine: exercise has among the strongest evidence of any non-drug intervention in Parkinson's¹, though no intervention has yet been proven to slow the disease. Boxing, tandem cycling, dance, tai chi and high-intensity treadmill walking all show benefits. In a large observational registry, people who started exercising earlier, at least 2.5 hours a week, had a slower decline in quality of life⁷.

💊

Conventional / Medical Approach

Dopaminergic medications, surgical options (DBS), emerging disease-modifying trials

First-Line

Carbidopa/levodopa, most effective symptomatic treatment

Younger Patients

Dopamine agonists, MAO-B inhibitors may be initiated first to delay levodopa-induced dyskinesias

Advanced Disease

Deep brain stimulation (DBS), focused ultrasound, intestinal levodopa gel

Disease-Modifying

No FDA-approved disease-modifying therapy yet; multiple trials ongoing

Conventional Approach Includes

Carbidopa/levodopa: the most effective symptomatic treatment, with substantial motor improvement. Side effects emerge over years: motor fluctuations (wearing off), dyskinesias.
Dopamine agonists: pramipexole, ropinirole, rotigotine patch. Less risk of dyskinesias. Side effects: impulse control disorders (gambling, hypersexuality), sleep attacks, hallucinations.
MAO-B inhibitors: selegiline, rasagiline, safinamide. Modest symptomatic effect.
COMT inhibitors: entacapone, opicapone; extend levodopa effect. Used for wearing off.
Amantadine: useful for dyskinesias and tremor. An extended-release form reduces dyskinesias.
Anticholinergics: trihexyphenidyl, benztropine, for tremor; mostly in younger patients (cognitive side effects in older).
Deep brain stimulation (DBS): electrode in subthalamic nucleus or globus pallidus. Substantial improvement in motor fluctuations and dyskinesias. Doesn't help non-motor symptoms.
Focused ultrasound (FUS) thalamotomy: non-invasive ablation for tremor
Apomorphine: pen/pump for severe "off" periods
Levodopa-carbidopa intestinal gel: jejunal infusion for advanced disease with motor fluctuations
Non-motor management: SSRIs for depression, modafinil for daytime sleepiness, clonazepam for REM sleep behavior disorder, droxidopa for orthostatic hypotension

⚠️ Important Medication Notes: Take levodopa 30 to 60 minutes before meals (protein interferes with absorption). Avoid sudden discontinuation: risk of a neuroleptic malignant-like syndrome¹⁴. Avoid medications that block dopamine (most antipsychotics, metoclopramide, prochlorperazine).

Supplement Protocol

Evidence-Based Supplements for Parkinson's Disease

CoQ10 and creatine failed in large trials²¹³; B12 status is worth checking, as is vitamin D where deficiency is suspected². Always coordinate with your neurologist; interactions exist.

Supplement	What it is for	Typical range	Timing	Notes & cautions
Coenzyme Q10 (Ubiquinol)	A large randomized trial at high dose showed no benefit and was stopped early for futility².	Not recommended for slowing Parkinson's (a large trial found no benefit)	Not applicable	It may interact with a vitamin K antagonist blood thinner and with insulin; check with your prescriber first².
Vitamin D3	Deficiency is common; low levels correlate with worse motor symptoms in observational studies. In a 12-⁠month randomized trial in 114 people, vitamin D3 kept disease stage steadier than placebo, but only in two gene variants, and this needs confirming¹⁷.	Amount set by your prescriber	With fat meal	Pair with K2, amount set by your prescriber. If you take warfarin, clear any vitamin K supplement with the clinician managing your anticoagulation before starting or stopping it: vitamin K antagonizes warfarin, and changing your intake destabilizes the INR. Consistency matters more than avoidance. This does not apply in the same way to direct oral anticoagulants such as apixaban or rivaroxaban, but tell your prescriber about any supplement you take.
Omega-⁠3 (EPA/DHA)	Anti-inflammatory and supports neuronal membranes. One pilot trial in 31 people with depression found fish oil lowered depression scores, a result that needs a larger trial¹⁸.	Amount set by your prescriber	With fat meal	Fish oil may lengthen clotting times with a vitamin K antagonist blood thinner; tell your prescriber if you take one¹⁹. In heart trials, fish oil supplements raised the risk of atrial fibrillation, an irregular heartbeat, more so at higher doses²⁰, so agree on the amount with your prescriber first.
Creatine	A large five-year randomized trial found no benefit¹³.	Not recommended for slowing Parkinson's (a large trial found no benefit)	Not applicable	Well tolerated in the trial, but without benefit.
B-Complex (B12, Folate)	Deficiency common in Parkinson's (levodopa increases homocysteine). Critical for neuronal function.	Amount set by your prescriber	Morning	Folic acid works for people with MTHFR variants; methylfolate is an alternative, not a requirement.
Curcumin	Anti-inflammatory. In laboratory studies it acts on amyloid and on alpha-synuclein clumping; this has not been shown in people.	Amount set by your prescriber	With fat meal	Discuss with neurologist before starting. Liver damage has been reported with highly bioavailable forms; stop and seek advice if you notice tiredness, nausea, dark urine or yellowing skin. It may be unsafe in pregnancy²¹. If you take a blood thinner, ask first, as turmeric may increase bleeding risk.
Probiotics (Specific Strains)	May help constipation in Parkinson's²⁷, but the evidence is limited and effects differ from one strain to another.	Amount set by your prescriber	With or without food	Consistent daily use needed for benefit. Use caution with a weakened immune system or a central line, as bloodstream infections from probiotics have been reported; agree on it with your team.
Mucuna pruriens (Velvet Bean)²²	Natural source of levodopa. Used in Ayurveda. A review of small trials reported a faster, longer response than the standard medicine but called the evidence limited²².	Discuss with your neurologist; levodopa content varies between products²²	Discuss with neurologist	Caution: Cannot be combined safely with synthetic levodopa without medical supervision. Discuss seriously with neurologist.

References & Evidence Notes

Each numbered entry below is either a source you can follow or a note setting out what the evidence does and does not support. Both are numbered together so the markers in the text line up.

Last reviewed October 20, 2026. Supplement entries are cross-checked against the NIH National Center for Complementary and Integrative Health and the Linus Pauling Institute Micronutrient Information Center.²⁶ The single most practical nutrition fact in Parkinson's is about timing, not content. Dietary protein competes with levodopa for the same intestinal and blood-brain transporter, so taking levodopa 30 to 60 minutes before meals, and shifting most protein to the evening, measurably improves how well the medication works. That is a real intervention, and the diet section describes it. Two cautions. Never stop or abruptly reduce Parkinson's medication: sudden withdrawal can cause a neuroleptic malignant-like syndrome, which is life-threatening. And Mucuna pruriens contains actual levodopa in unstandardized amounts, so combining it with prescribed levodopa is a genuine drug interaction rather than a supplement question.

On exercise: exercise has among the strongest evidence of any non-pharmacological intervention in Parkinson's, improving motor function, gait and quality of life, with a randomized trial of high-intensity treadmill exercise supporting its feasibility and effect on motor symptoms, PubMed 29228079. Physical therapy, boxing and dance programs are all supported. This is the intervention worth prioritizing above any supplement on this page. ↩
On supplements and diet: coffee and higher urate levels are associated with lower Parkinson's risk in cohort studies, which is an association rather than a treatment. Coenzyme Q10 was tested at high dose in a large randomized trial and showed no benefit, with the trial stopped early for futility; NCCIH reports that a later evaluation concluded CoQ10 is not helpful for Parkinson's symptoms, and that it may interact with the vitamin K antagonist blood thinner and with insulin, NCCIH, coenzyme Q10. A Mediterranean or MIND dietary pattern is associated with slower progression observationally. Vitamin D and B12 status are worth checking, the latter because levodopa-carbidopa can lower B12 and contribute to neuropathy. ↩
On what is lost and why: NHS guidance explains that Parkinson's is caused by loss of the nerve cells in the substantia nigra that make dopamine, and that symptoms usually start only when around 50% of the nerve cell activity there has been lost. Why the cells are lost is not known; a combination of genetic changes and environmental factors is thought to be responsible, several genetic factors raise the risk though inherited forms are rare, and the evidence linking pesticides or pollution is inconclusive. Some antipsychotic medicines cause a drug-induced parkinsonism that usually improves once the medicine is stopped, NHS, causes of Parkinson's disease. ↩
On the disease: Parkinson's involves loss of dopaminergic neurons in the substantia nigra with alpha-synuclein aggregation, and is increasingly understood as multi-system, with constipation, loss of smell and REM sleep behavior disorder often preceding motor symptoms by years. Non-motor symptoms frequently affect quality of life more than tremor does. ↩
On how many people have Parkinson's: the Parkinson's Foundation estimates that about 1.1 million people in the US live with Parkinson's and that nearly 90,000 are diagnosed each year; age is the primary risk factor, about 4% of people are diagnosed before age 50, and men are 1.5 times more likely to have it than women, Parkinson's Foundation, statistics. ↩
On depression: a systematic review of prevalence studies found major depression in 17% of people with Parkinson's, minor depression in 22% and clinically significant depressive symptoms in 35%, and concluded that major depression is substantial but less common than generally assumed, PubMed 17987654. ↩
On how much exercise: the Parkinson's Foundation recommends at least 2.5 hours of exercise a week, covering aerobic activity, strength training, balance and flexibility, and lists tai chi, dance and non-contact boxing among the activities with benefits for Parkinson's symptoms, and reports from its observational outcomes registry that people who started exercising at least 2.5 hours a week earlier in the disease had a slower decline in quality of life than those who started later, Parkinson's Foundation, accessed 2026. ↩
On REM sleep behavior disorder: in an international study of 1,280 people with REM sleep behavior disorder and no other diagnosis, 6.3% a year went on to develop an overt neurodegenerative condition such as Parkinson's disease, dementia with Lewy bodies or multiple system atrophy, and 73.5% had done so after 12 years of follow-up, PubMed 30789229. ↩
On dementia: a systematic review estimated that 24 to 31% of people with Parkinson's have dementia at any one time, PubMed 16041803, and in a cohort followed for 20 years from diagnosis, dementia was present in 83% of those still alive, PubMed 18307261. ↩
On pesticides: in a case-control study within a US agricultural cohort, Parkinson's was associated with use of rotenone and of paraquat, each with an odds ratio of 2.5, PubMed 21269927; NHS guidance describes the overall evidence linking environmental factors to Parkinson's as inconclusive, NHS, causes of Parkinson's disease. ↩
On the alpha-synuclein seed amplification test: in 1,123 participants, the spinal fluid test was positive in 87.7% of people with Parkinson's and negative in 96.3% of healthy controls, with lower positivity in some genetic forms, PubMed 37059509. ↩
On constipation, which is not a minor symptom here. Constipation is one of the most common and earliest signs of Parkinson's, and slow stomach emptying means the main dopamine-replacement medicine cannot be absorbed in time, producing dose failures, Parkinson's Foundation, digestive symptoms. Treating constipation with fluid, fiber and, where needed, polyethylene glycol laxatives improves medication reliability as well as comfort. ↩
On creatine: a randomized placebo-controlled trial in 1,741 people with early, treated Parkinson's, who took creatine for at least five years, was stopped early for futility and found no improvement in clinical outcomes, PubMed 25668262. ↩
On sudden withdrawal. Abrupt discontinuation or a large reduction of dopaminergic medication can precipitate a neuroleptic malignant-like syndrome with rigidity, fever, autonomic instability and raised creatine kinase, which is a medical emergency. Sudden withdrawal of anti-parkinsonian medication, levodopa in particular, is the most common trigger for it, PubMed 36320988. This also applies to missed doses during hospital admissions, where Parkinson's medication timing is frequently disrupted, and it is worth raising proactively with any admitting team. ↩
On levodopa and protein. Levodopa is absorbed by the large neutral amino acid transporter and competes with dietary amino acids at the gut and at the blood-brain barrier. Taking it 30 to 60 minutes before meals, and redistributing protein toward the evening meal, improves motor response in patients with fluctuations. The aim is redistribution, not restriction: protein intake must stay adequate, because weight loss and sarcopenia are common in Parkinson's and worsen outcomes. NICE advises discussing a diet with most of the protein at the final main meal of the day for people with motor fluctuations, and advises against any reduction in total daily protein, NICE NG71. ↩
On dairy: in two large US cohorts of 129,346 women and men followed for about 25 years, eating at least 3 servings a day of low-fat dairy was linked to a higher risk of Parkinson's than eating none (hazard ratio 1.34), driven by skim and low-fat milk, and a meta-analysis adding other prospective studies linked higher total dairy intake to a modestly higher risk (hazard ratio 1.27). These are associations, not proof that dairy causes Parkinson's, PubMed 28596209. ↩
On vitamin D: in a 12-⁠month randomized placebo-controlled trial in 114 people with Parkinson's, vitamin D3 prevented worsening of disease stage compared with placebo, with the effect confined to two variants of the vitamin D receptor gene; the authors say it may stabilize the disease only for a short period and the effect may not be specific to Parkinson's, PubMed 23485413. ↩
On fish oil and depression: a double-blind pilot trial in 31 people with Parkinson's and major depression found fish oil lowered depression scores over three months, and the authors say the result needs replication in a larger sample, PubMed 18485485. ↩
On fish oil and blood thinners: NIH guidance notes that fish oil might prolong clotting times when taken with the vitamin K antagonist blood thinner, and that people taking omega-⁠3 products with anticoagulants should have their clotting monitored periodically, NIH Office of Dietary Supplements, omega-⁠3 fatty acids. ↩
Gencer B, Djousse L, Al-Ramady OT, Cook NR, Manson JE, Albert CM. Effect of long-term marine omega-⁠3 fatty acids supplementation on the risk of atrial fibrillation in randomized controlled trials of cardiovascular outcomes: a systematic review and meta-analysis. Circulation. 2021;144(25):1981-⁠1990. PubMed 34612056. Seven trials with 81,210 people followed for about 5 years: omega-⁠3 supplements were linked to a higher risk of atrial fibrillation (hazard ratio 1.25), more so in the trials giving higher doses (hazard ratio 1.49), and the risk rose with the dose. ↩
On curcumin safety: NCCIH notes that conventional turmeric or curcumin is likely safe for up to 2 or 3 months, that liver damage has been reported in some people taking forms made more bioavailable, that anyone who notices fatigue, nausea, poor appetite, dark urine or jaundice should stop at once and talk with a clinician, and that turmeric supplements may be unsafe in pregnancy, NCCIH, turmeric. ↩
On Mucuna pruriens. Velvet bean is a natural source of levodopa and has small trials showing effect, but the levodopa content of preparations varies and it lacks the peripheral decarboxylase inhibitor that carbidopa provides, which increases nausea and peripheral side effects. A systematic review complicates that last point: it found Mucuna associated with a faster and longer response, with fewer adverse events, and reported no dyskinesia, while noting the clinical evidence is limited, PubMed 40860042. That review compared it with levodopa rather than added to it, so it does not answer the question that matters here: combining it with prescribed levodopa risks additive dopaminergic effects and dyskinesia. It is a pharmacological decision for a neurologist, not a supplement choice. ↩
On the course of treatment: NHS guidance says a specialist bases the diagnosis on symptoms, history and examination, that treatment may not be needed at first while symptoms are mild, and that most people eventually need the main dopamine-replacement medicine, started at a very small dose and increased gradually. Its effects can become shorter-lasting over the years, long-term use is linked to involuntary movements and on-off effects, and deep brain stimulation can ease symptoms for some people. With advances in treatment most people now have a normal or near-normal life expectancy, NHS, treatment for Parkinson's disease; NHS, Parkinson's disease. ↩
On protein, stopping medicines and supportive therapy: NICE advises discussing a diet with most of the protein at the final main meal of the day for people on dopamine-replacement medicine who have motor fluctuations, and advises against reducing total daily protein. It states that antiparkinsonian medicines should not be withdrawn abruptly or allowed to fail suddenly, because of the risk of acute akinesia or neuroleptic malignant syndrome, and that in the hospital they should be given at the appropriate times. It recommends asking about hallucinations after medicine changes, Parkinson's-specific physical therapy for balance or movement problems, and speech and language therapy for problems with communication, swallowing or saliva, NICE NG71. ↩
On emergencies: NHS guidance advises calling emergency services after a fall with a possible injury to the head, back, neck or hip, NHS, falls, and getting help immediately when someone suddenly becomes confused, which can include seeing or hearing things that are not there, NHS, confusion. Coughing or choking when eating or drinking, or difficulty swallowing, needs an urgent appointment, NHS, dysphagia; a choking person who cannot speak or is struggling to breathe needs first aid at once and a call to 911, MedlinePlus, choking. ↩

In 72 people with Parkinson's and constipation, a multi-strain probiotic taken for 4 weeks raised the number of spontaneous bowel movements by about 1.3 a week compared with placebo; it was a small, short, single-center trial; longer-term benefit and safety were not tested. ↩

Symptom	What happens
Motor Symptoms
Resting Tremor	"Pill-rolling" tremor at rest, usually starts in one hand. Disappears with action. Often the first noticed symptom. Asymmetric onset is characteristic.
Bradykinesia (Slowness)	Slowness of movement initiation and execution. Smaller handwriting (micrographia), reduced facial expression (hypomimia), softer voice (hypophonia).
Rigidity	Increased muscle tone; "cogwheel" rigidity on exam. Stiffness in limbs, neck. Often associated with discomfort or pain.
Postural Instability & Gait Changes	Shuffling steps, reduced arm swing, freezing of gait, falls. Later in disease. Falls are a major cause of morbidity.
Non-Motor (Often Earlier)
Constipation	May precede motor symptoms by 10 to 20 years. Slow gut transit. Critical to address: it affects medication absorption and quality of life.
Loss of Smell (Anosmia)	Reduced or absent sense of smell. May precede motor symptoms by 5 to 10 years. The olfactory bulb is one of the first structures affected.
REM Sleep Behavior Disorder	Acting out dreams, kicking, punching, falling out of bed. A strong early sign: in a large international study, 73.5% had developed Parkinson's or a related condition after 12 years⁸.
Depression, Anxiety, Cognitive Changes	Depression: clinically significant depressive symptoms in about 35%⁶. Anxiety, apathy, cognitive slowing common. Dementia in about 24 to 31%, more often as the disease advances (Parkinson's disease dementia)⁹.

Cause	How It Contributes to Parkinson's Disease	What Helps
Loss of dopamine-making nerve cells	Less dopamine means movements become slow and abnormal, and symptoms usually start only when around 50% of the nerve cell activity in the substantia nigra has been lost³	Dopamine-replacement medicine prescribed by your care team, with exercise alongside it, as the treatment section describes
Age	Age is the main risk factor, and only about 4% of people are diagnosed before age 50 ⁵	Nothing changes age; regular exercise and a Mediterranean-style diet are the lifestyle measures this page supports
Genes	Several genetic factors raise the risk, but inheriting Parkinson's directly from a parent is rare³	Genetic testing for young onset or a strong family history, as the diagnosis section describes, with counseling for the family
Pesticides	In a US farming study, use of the pesticides paraquat or rotenone was linked to Parkinson's¹⁰, though the overall evidence for environmental causes is inconclusive³	Limiting pesticide exposure at work and at home, as the treatment section advises
Being male	Men are about 1.5 times more likely to have Parkinson's than women⁵	Nothing to change; know the early signs in the symptoms section and see a clinician about them
Medicines that block dopamine	Some antipsychotic medicines can cause drug-induced parkinsonism, which usually improves once the medicine is stopped³	A medication review with your prescriber; never stop a prescribed medicine on your own. The treatment section lists the medicine classes that block dopamine

Test	What it shows
Clinical Diagnosis
Clinical Examination	Diagnosis is primarily clinical; a neurologist examines for the cardinal features: bradykinesia + tremor or rigidity. Asymmetric onset supports the diagnosis. Neurologists use the Movement Disorder Society diagnostic criteria.
Response to Levodopa	Clear improvement with levodopa supports diagnosis (and is often used therapeutically as a diagnostic test). Poor response suggests atypical parkinsonism.
Dopamine Transporter Imaging (DaT-SPECT)	SPECT imaging of dopamine transporters in striatum. Distinguishes Parkinson's from essential tremor and drug-induced parkinsonism. Used when diagnosis unclear.
Alpha-Synuclein Seed Amplification Assay	A newer test that detects misfolded alpha-synuclein in spinal fluid or skin biopsy. In a large study the spinal fluid test was positive in 88% of people with Parkinson's and negative in 96% of healthy controls¹¹. May enable earlier diagnosis and clinical trial enrollment.
Workup to Exclude Other Causes
Brain MRI	Rules out other causes: strokes, normal pressure hydrocephalus or tumors. Parkinson's MRI typically normal early; atrophy patterns may suggest atypical parkinsonisms.
Wilson's Disease Workup	In young-onset cases (<50): ceruloplasmin, urinary copper, slit lamp for Kayser-Fleischer rings. Wilson's is a treatable cause of parkinsonism.
Heavy Metal Testing	Especially manganese (welders, miners). Pesticide exposure history (paraquat, rotenone associated with Parkinson's). Modifiable in some cases.
Genetic Testing (Selected)	For young-onset, strong family history. LRRK2, GBA, SNCA, PRKN, PINK1. Implications for treatment trials and family counseling.

What to eat or do	Details
✅ Prioritize:
Coffee (2 to 3 cups/day)	Associated with lower Parkinson's risk in cohort studies²; not shown to slow progression. Black or with minimal additions.
High Fiber	Combat constipation, support microbiome. Ground flax (1 to 2 tbsp/day), prunes, beans, vegetables, whole grains. Critical for medication absorption.
Fatty Fish (2 to 3x/week)	Omega-⁠3 fats, as part of a Mediterranean-style pattern². Wild salmon, sardines, Atlantic mackerel.
Green Tea	EGCG affects alpha-synuclein clumping in lab studies; these are not trials in people. 2 to 3 cups/day.
Mediterranean / MIND Diet	Vegetables, fruits, olive oil, nuts, fatty fish, legumes. Associated with slower progression in observational studies².
❌ Limit / Time Carefully:
Protein Timing (Not Avoidance)	Don't cut protein overall, which risks weight and muscle loss; agree on timing with your care team¹⁵. The main dopamine-replacement medicine is often taken 30 to 60 min before meals, and some people eat most protein at the evening meal¹⁵.
Excessive Dairy	High dairy intake (especially low-fat dairy) associated with a modestly increased risk of developing Parkinson's in cohort studies¹⁶. Moderate consumption fine.
Refined Carbs & Sugar	Low in fiber, so they do little for constipation; swap sodas, sweets and white bread for the high-fiber foods above.
Pesticides	Pesticide exposure (paraquat, rotenone, organochlorines) associated with Parkinson's. The evidence is for farm use of pesticides, and NHS guidance calls the overall link inconclusive¹⁰.
Heavy Alcohol	Worsens falls risk, sleep, cognition. Interacts with Parkinson's medications. Light to moderate use may be neutral but limit.
