List major classes of degenerative disorders
- dementing diseases
- movement disorders
- motor neuron disease
list dementing diseases
- Alzheimer’s Disease
- Lewy Body Disease Spectrum (LBD)
- Frontotemporal Dementia (FTD)
List movement disorders
- Parkinson’s disease
- Multiple systems atrophy (MSA)
- Progressive Supranuclear Palsy (PSP)
- Huntington’s disease
- Spinocerebellar ataxias
List motor neurons diseases
- Spinal muscular atrophy (SMA)
- Amyotrophic lateral sclerosis (ALS)
- Primary lateral sclerosis (PLS)
dementing disease signs
- Impaired language
- Impaired long term memory
- Impaired planning, behavior, judgment, executive control
- Impaired short term memory
Movement disorder categories
- basal ganglia disorder
2. cerebellar disorders (HANDS Tremor)
Basal ganglia disorder signs
- Tremor (usually resting)
- Hypokinesis
- Hyperkinesis
Hypokinesis:
bradykinesis and rigidity
Hyperkinesis:
- chorea
- athetosis (involuntary writhing movements)
- akathisia (restlessness)
Cerebellar disorders (HANDS Tremor) signs
- Hypotonia
- Ataxia/Asynergia
- Nystagmus
- Dysarthria
- Stance and gait disequilibrium
- Tremor (usually intention)
Overlap of Progressive Supranuclear Palsy
tauopathy that manifests as a movement disorder
Overlap of AD
tauopathy that manifests as dementing diseases
List synucleinopathies
- parkinson’s disease
2. Multiple system atrophy
Parkinson’s disease histology hallmarks
- Lewy bodies
- Lewy neuritis (proteinacious structures around neurons)
- Substantia nigra degeneration (with few neurons and gliosis)
Multiple system atrophy
histology hallmarks
- Glial cytoplasmic inclusions (inclusions are synuclein protein)
- Gliosis and glial scars
- Neuronal inclusions
- Diffuse involvement/degeneration of brainstem, putamen, white matter, and cerebellum
various disease processes affecting specific neuroanatomic site manifest ______
similar symptoms.
damage to the substantia nigra can cause
- parkinson’s disease
- multiple system atrophy
- progressive supranuclear palsy
- corticobasal degneration
All present with parkinsonian-like symptoms
What is the role the frontal lobes in human cognition?
- Voluntary movement
- Language production (left)
- Motor prosody - inflection of speech, homologous area on right side
- Comportment
- Executive Function/ understand emotions of others
What is the role the temporal lobe in human cognition?
- Audition
- Language comprehension
- Sensory prosody - understanding inflection, located on right side
- Memory
- -Hippocampus - remember H.M. removal of bilateral hippocampi for intractable epilepsy - Emotion
- -Limbic system and Papaz circuit
What is the role the parietal lobes in human cognition?
- Tactile sensation
- Visuospatial function
- Attention ( R )
- Reading (L)
- Writing (L)
- Calculation (L)
What is the role the occipital lobes in human cognition?
- Vision
- Visual Perception
- Visual Recognition
