Multiple system atrophy (MSA) is a rare neurodegenerative disorder [1] characterized by tremors, slow movement, muscle rigidity, postural instability (collectively ...
They include multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). Dementia with Lewy bodies (DLB), may or may not be part of the PD spectrum, but it is increasingly recognized as the second-most common type of neurodegenerative dementia after Alzheimer's disease.
[12] [13] Further research identified multiple causes for these syndromic findings, now grouped as primary autonomic disorders (also called primary dysautonomia), including Pure Autonomic Failure, Multiple System Atrophy, and Parkinson's. The primary differentiating characteristic of Pure autonomic failure is decreased circulation and synthesis ...
Cerebral atrophy; Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy; Cerebral dysgenesis–neuropathy–ichthyosis–keratoderma syndrome; Cerebral gigantism; Cerebral palsy; Cerebral vasculitis; Cerebrospinal fluid leak; Cervical spinal stenosis; Charcot–Marie–Tooth disease; Chiari malformation; Chorea
In multiple system atrophy, autonomic dysfunction appears earlier and is more severe, [39] and is accompanied by uncoordinated movements, while visual hallucinations and fluctuating cognition are less common than in DLB. [150] Urinary difficulty is one of the earliest symptoms with multiple system atrophy, and is often severe. [70]
Upper motor neuron lesions occur in the brain or the spinal cord as the result of stroke, multiple sclerosis, traumatic brain injury, cerebral palsy, atypical parkinsonisms, multiple system atrophy, and amyotrophic lateral sclerosis.
Progressive supranuclear palsy (PSP) is a late-onset neurodegenerative disease involving the gradual deterioration and death of specific volumes of the brain. [1] [2] The condition leads to symptoms including loss of balance, slowing of movement, difficulty moving the eyes, and cognitive impairment. [1]
DaTSCAN is indicated in cases of tremor when its origin is uncertain. Although this method can distinguish essential tremor from Parkinson's syndrome, it is unable to distinguish between Parkinson's disease, Dementia with Lewy bodies, Parkinson's disease dementia, [3] multiple system atrophy or progressive supranuclear palsy.
