Parkinsonian disorders

1- Parkinson disease

2-Multiple system Atrophy aka Shy Drager Syndrome( The most common signs of dysautonomia in pathologically confirmed cases are bladder dysfunction (89%), particularly urinary incontinence (44%) and urinary retention (26%), bowel dysfunction (77%), particularly constipation (46%) and fecal incontinence (27%), orthostatic hypotension (75%), sexual dysfunction (64%), RBD (54%), sweating dysfunction (40%), sleep apnea (37%), and nocturnal stridor (30%) . In contrast to PD, MSA-P usually presents with symmetrical parkinsonism, often without tremor, with early instability and falls. Most patients become wheelchair bound within 5 years after onset).

3-Progressive Supranuclear Palsy(as a progressive illness characterized by vertical supranuclear ophthalmoplegia, axial rigidity, pseudobulbar palsy, and mild dementia, PSP is the second most common form of neurodegenerative atypical parkinsonism).

4-corticobasal degeneration

5-Frontotemporal degeneration with parkinsonism(Pick disease, pallidopontonigral degeneration, disinhibitiondementia-
parkinsonism-amyotrophy, familial multiple system tauopathy with presenile dementia, familial subcortical gliosis,
frontotemporal dementia (FTD), FTD with ALS, FTD with inclusion body myopathy, and FTDP-17).

6-Parkinsonism -Dementia complex of guam

7-guadeloupean Parkinsonism

8-Vascular Parkinsonism

9-Bilateral Striaopallidodentate Calcification(Fahr Disease}

10-Post Encephlitis Parkinsonism

11-Drug -Induced Parkinsonism(anti psychotic, anti dopaminergic emetics, reserpine ,tetrabenazine,aripiprazole,SSRI,Lithium,methyldopa,Vapproic acid,flunarizine and cinnarizine)

12-Toxin- Induced Parkinsonism(MPTP produced by monoamine oxidase, 1-methyl-4-phenylpropion-
oxypiperidine (MPP+), Co poisoning).
