Selegiline (deprenyl) is a drug similar in structure to phenylethylamine, a neurotransmitter and an influencer of serotonin and dopamine.
It is also an enzyme blocker (belongs to a group of chemicals that are called MAO-B inhibitors – monoamine oxidase type B inhibitors) which works by slowing the breakdown of certain natural substances in the brain. This helps to ease stiffness, tremor, and slow movement – all symptoms of Parkinson’s disease.
It is sold under the trade name Emsam for the treatment of major depression disorder (MDD), and Zelapar and Eldepryl for the treatment of Parkinson’s disease (PD).
This drug is typically used to control the symptoms of PD, a disorder of the nervous system which causes difficulties with muscle control, movement, and balance. Affecting 1 to 2% of people older than 60 years, Parkinson’s disease is the 2nd most common neurodegenerative disorder.
Note – it does not cure PD, however, it may improve muscle stiffness, shakiness, loss of normal movement. Also, this medication may be given with levodopa (one of the main medications used to treat Parkinson’s symptoms) upon the onset of this disability.
It comes in capsule and tablet forms. The tablet is typically taken once per day and the capsule is taken two times per day. Do not use doses higher than this, as there is no evidence that there is any greater effect of the drug, but it will only increase the risk of adverse effects at higher doses.

Low dopamine levels in the brain are responsible for many of the symptoms of PD, therefore, this drug works by rebalancing the levels of dopamine.
Its brand name is Azilect.

Selegiline vs Rasagiline – Which Is Better For Parkinson’s Disease?
Selegiline is a medication which is used to cure the symptoms of Parkinson’s disease, especially it helps to prevent the loss of balance and coordination, muscular tremors, and the stiffness of certain parts of the body.
Rasagiline is also used either alone or in combination with other drugs to treat the symptoms of PD, including – stiffness, shakiness, and difficulty with movements.
According to research, there are no differences between these two medications regarding their effect on reducing the symptoms of PD, especially in patients with early-stage disease.

#1 Omega-3 Foods
Increasing your intake of omega-3 fatty acids will help reduce inflammation and elevate dopamine levels. Food rich in omega 3 includes – flax seeds, chia seeds, walnuts, pecans, sesame seeds, mung beans, pistachios, and macadamia nuts.
Cannabis can improve the nonmotor and motor symptoms of PS, according to a study conducted at the Rabin Medical Center and Tel Aviv University.
