Corticobasal degeneration (CBD) is a rare neurodegenerative disease involving the cerebral cortex and the basal ganglia. [1] CBD symptoms typically begin in people from 50 to 70 years of age, and typical survival before death is eight years.
Corticobasal syndrome (CBS) is a rare, progressive atypical Parkinsonism syndrome and is a tauopathy related to frontotemporal dementia. [ 1 ] [ 2 ] CBS is typically caused by the deposit of tau proteins forming in different areas of the brain.
Corticobasal syndrome and degeneration, and progressive supranuclear palsy, are usually distinguished from DLB by history and examination. Motor movements in corticobasal syndrome are asymmetrical. There are differences in posture, gaze and facial expressions in the most common variants of progressive supranuclear palsy, and falling backwards ...
There are no treatment options available to delay the onset of dementia. [169] Acetylcholinesterase inhibitors are often used early in the disorder course; however, benefit is generally small. [ 8 ] [ 170 ] More than half of people with dementia may experience psychological or behavioral symptoms including agitation, sleep problems, aggression ...
Corticobasal degeneration (CBD) is an increasingly acknowledged neurodegenerative disorder characterized by both motor and cognitive dysfunction. In affected regions, histological examination reveals pronounced neuronal loss accompanied by spongiosis and gliosis, cortical ballooned cells, and notable intracytoplasmic filamentous tau pathology ...

The most severe brain atrophy appears to be associated with behavioral variant FTD, and corticobasal degeneration. [42] With regard to the genetic defects that have been found, repeat expansion in the C9orf72 gene is considered a major contribution to FTLD, although defects in the GRN and MAPT genes are also associated with it. [43]
One candidate is the tracer [18 F]FDDNP, which is retained in the brain in individuals with several dementing disorders such as Alzheimer's disease, Down syndrome, progressive supranuclear palsy, corticobasal degeneration, familial frontotemporal dementia, and Creutzfeldt–Jakob disease. [27]
