Parkinson’s Plus
Hypokinetic symptoms prominent in “mixed dysarthric conditions: PSP Progressive Supranuclear Palsy, MS Multiple Systems Atrophy, CBD Corticobasal degeneration; maybe w/ hyperkinesia, ataxia, spasticity
MSA
multiple syste atrophy; 3/100,000; onset: 50, survival ~9 years; neuronal loss in basal ganglia, substantial nigra, cerebellum, brainstem nuclei, corticospinal tracts, cerebral cortex
MSA-P (Parkinsonian)
used to be Striatonigral generation; nerve loss in basal ganglia and substantial nigra; HYPOKINETIC, maybe w/ spasticity and ataxia
MSA-C (cerebellar)
used to be olivopontocerebellar atrophy; nerve loss in cerebellar circuit (middle cerebellar peduncles, white matter, parking cells, pontine, olivary, arcuate nuclei); ATAXIC, maybe w/ spasticity and hypokinesia
MSA-A (autonomic)
used to by Shy-Drager syndrome; degeneration of motor components of autonomic and somatic CNS; Autonomic deficits: decreased blood pressure & respiration, incontinence, impotence; gait disturbance; dysarthria (ataxia, hypo, spastic) and dysphagia
CBD Corticobasal degeneration
Frontal & parietal lobe atropy, neuronal death in basal ganglia; onset: 50-70; survival: 5-15; asymmetric limb rigidity/dyskinesia, cog deficits, yes/no reversal, apraxia of speech; HYPO and SPASTIC, maybe w/ ataxic and hyper
Progressive supranuclear palsy PSP
neuroal atrophy in cortex (frontal, maybe temporal lobes), basal ganglia, thalamus, hypothalamus, subthalamus, brainstem nuclei; 1.4/100,000; more in men than women; onset: 55-70, survival: 6-7; vertical gaze paralysis, symmetric parkinsonism (rigid, bradykinesia, postural instability), personality & cog changes; dysphagia & dysarthria (hypo, spastic, ataxic)
Wilson’s Disease
impairment in processing copper; brown ring around cornea, tranquil rigidity, wing-beating tremor; med tx does not help dysarthria
Hepatocerebral degeneration
chronic liver disease; lem tremor, choreoathetosis, ataxic gait
Hypoxic encephalopathy
damage to basal ganglia, cortex, brainstem nuclei; hypo hyper spastic and ataxic dysarthria (not studied)
TBI
imprecise arctic, hyper nasal, strained, mono pitch & loud, excess equal stress, repiratory incoordination; cog deficits
Motor Neuron Disease
ALS (UMN & LMN); Progressive bulbar palsy (LMN CRANIAL) 25%; Primary muscular atrophy (LMN Spinal) 5%; Primary lateral sclerosis (UMN only) 0.5%
Amyotrophic Lateral Sclerosis
aka Lou Gehrig; 5% familial, 1-5/100,000; men > women; onset: 40-70, survival ~1-5, 12+; death by respiratory failure; degeneration of UMN and LMN; unable to walk, limb wasting/atrophy, respiratory weakness, dysphagia, dysarthria (Flaccid spastic mix)
