diseases that cause parkinsonism + other symptoms:
- multi system atrophy
- dementia with lewey bodies
- progressive supranuclear palsy
- corticobasal degeneration
6
what is multi system atrophy
group of disorders that progressively affect the central and autonomic nervous by system damaged oligodentrocytes (myelination) by accumulation of alpha synuclein
two types- MSA-P: characterised by parkinsons motor symptoms, deteriorates faster. MSA-C: cerebellar, lack of coordination and balance, intention tremor, slurred speech and difficulty swallowing (dysphasia)
both types characterised by autonomic symptoms- orthostatic hypotension, constipation, increased sweating, sleep apnoea, sexual dysfunction
7
what protein is found in dementia with lewey bodies

8
what are the symptoms of DLB
cognitive impairments, visual hallucinations, inability to focus, inflexible thinking and paranoia. DLB patients initially have these cognitive symptoms but also develop motor symptoms similar to PD such as bradykinesia, tremor, rigidity, and shuffling walk. Similar to PD, DLB patients also have REM sleep behavior disorder in which they act out their dreams.

-occipital cortex-> oculomotor nucleus -> CN3 and medial longitudinal fasciulus -> pontine horizontal gaze centre
loss of voluntary movements of eye
as brainstem intact, all reflex conjugate eye movements normal
