Which of the following is NOT a disease affecting basal ganglia & brainstem? A. Multiple System Atrophy B. Huntington's Disease C. Progressive Supranuclear Palsy D. Pick's Disease
D. Pick’s Disease affects cerebral cortex
Parkinson Disease also affects basal ganglia & brainstem
Which of the following affect motor neurons? A. Alzheimer's Disease B. Parkinson Disease C. Huntington's Disease D. Amyotrophic Lateral Sclerosis
D
Two categories of clinical manifestation of neurodegenerative disease
Dementia
Movement disorders
T/F: Alzheimer’s Disease is relatively sparring of the occipital lobe.
True
Neuritic plaques found in all the following areas of the brain in Alzheimer's EXCEPT: A. Hippocampus B. Amygdala C. Neocortex D. Basal Ganglia
D
Secretory cleavage by _____ makes A-beta42 in neuritic plaques
Beta and gamma-secretase
Mutation that gain of function w/ increased production of A-beta42
All the following about neurofibrillary tangles are true EXCEPT:
A. Argyrophilic
B. Paired helical filaments in Pick’s Disease
C. Hyperphosphorylated forms of tau
D. Tau is encoded by gene 17q21
B. UNpaired helical filaments in Pick’s Disease
Paired helical filaments in Alzheimer’s Disease
T/F: Pick’s Disease mainly affects the parietal lobe.
False. Frontal lobe
Spares posterior superior temporaly gyrus
T/F: Neuritic plaques and amyloid angiopathy is found in Pick’s Disease.
False. Found in Alzheimer’s, not Pick’s
Neurofibrillary tangles found in both
Pick bodies =
Tau containing intraneuronal inclusion bodies
Spherical in neuronal cell bodies
Strongly argyrophilic
Found in pyramidal neurons, dentate granule cells in hippocampus, neocortex
Lewy bodies found in ____
Pathology appearance:
Parkinsonism
Eosinophilic core w/ outer halo
Needed for definitive diagnosis of Parkinson’s
Name the disease:
Loss of pigmented neurons in substantia nigra due to damages of dopaminergic neurons.
Parkinsonism
2nd most common cause of dementia
Dementia w/ Lewy Bodies (DLB)
Lewy-related neurites contain ____
Alpha-synuclein + material within neuropils
Dementia w/ Lewy Bodies present pathologically will all the following EXCEPT:
A. Cortical Lewy bodies
B. Lewy-related neurites
C. Neuritic plaques
D. Lipofuscin-like pigment in glial cells
E. Neurofibrillary tangles
D. Feature of Striatonigral degeneration (Multiple System Atrophy)
Grossly: pallor of substantia nigra and locus ceruleus
Multiple System Atrophy (MSA): Striatonigral degeneration predominated by
Parkinsonism
Striatonigral degeneration shows grossly w/ atrophy of putamen
Multiple System Atrophy (MSA): Olivopontocerebellar atrophy (OPCA) predominated by
Cerebellar signs
Multiple System Atrophy (MSA): Shy-Drager syndrome predominated by
autonomic failure
Glial inclusions are linked to ____
Multiple System Atrophy (MSA)
Caveat: not all cases of Olivopontocerebellar atrophy (OPCA) have glial inclusions
