==Overview==
==Overview==
The mainstay of therapy for motor symptoms of Parkinson disease are: Levodopa, dopamine agonists, monoamine oxidase (MAO) B inhibitors, anticholinergic agents, amantadine, catechol-O-methyl transferase (COMT) inhibitors, estrogen and other drugs such as [[Exenatide]], [[uric acid]], [[isradipine]], [[nilotinib]] and [[GDNF]] infusion.
Treatment choices for some of the nonmotor symptoms of PD are:
psychosi<nowiki/>s: [[quetiapine|quet]][[quetiapine|iapine]], [[clozapine|clozap]]<nowiki/>[[clozapine|ine]] and [[pimavanserin]].
Dementia: [[Cholinesterase inhibitors|C]]<nowiki/>[[Cholinesterase inhibitors|holinesterase inhibitors]] such as [[rivastigmine]] and [[donepezil]].
Fatigue: [[Amantadine]], [[methylphenidate]] and [[pemoline]].
<nowiki/>Depression: [[Amitriptyline]], [[desipramine]], [[citalopram]] ,[[paroxetine]], [[venlafaxine]], [[ropinirole]] and [[pramipexole]].
Constipati<nowiki/>on: Increasing [[Probiotic|probiotics]] and fibers, [[lubiprostone]] and [[polyethylene glycol]].
Sialorrhea: chewing gum and hard candy but in severe cases, [[botulinum toxin]] injection into [[Salivary gland|salivary glands]] .
Sexual dysfunction: [[sildenafil]] (for male)
Ortostatic hypotention: [[Fludrocortisone]], [[Sympathomimetic agents]] such as [[ephedrine]], [[pseudoephedrine]], [[methylphenidate|methylp]]<nowiki/>[[methylphenidate|henidate]] and<nowiki/> [[dextroamphetamine]].

Overview

The mainstay of therapy for motor symptoms of Parkinson disease are: Levodopa, dopamine agonists, monoamine oxidase (MAO) B inhibitors, anticholinergic agents, amantadine, catechol-O-methyl transferase (COMT) inhibitors, estrogen and other drugs such as Exenatide, uric acid, isradipine, nilotinib and GDNF infusion.

Treatment choices for some of the nonmotor symptoms of PD are:

psychosis: quetiapine, clozapine and pimavanserin.

Dementia: Cholinesterase inhibitors such as rivastigmine and donepezil.

Fatigue: Amantadine, methylphenidate and pemoline.

Depression: Amitriptyline, desipramine, citalopram ,paroxetine, venlafaxine, ropinirole and pramipexole.

Constipation: Increasing probiotics and fibers, lubiprostone and polyethylene glycol.

Sialorrhea: chewing gum and hard candy but in severe cases, botulinum toxin injection into salivary glands .

Sexual dysfunction: sildenafil (for male)

Ortostatic hypotention: Fludrocortisone, Sympathomimetic agents such as ephedrine, pseudoephedrine, methylphenidate and dextroamphetamine.

Medical Therapy

The mainstay of therapy for motor symptoms of Parkinson disease are:
