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.
CBS is the most common type of corticobasal degeneration (CBD) although the terms CBD and CBS have been used interchangeably in the past. [2] The other three phenotypes of CBD are: [1] frontal-behavioral dysexecutive-spatial syndrome (FBS) nonfluent/agrammatic variant of primary progressive aphasia (naPPA), and
Frontotemporal dementia (FTD), also called frontotemporal degeneration disease [1] or frontotemporal neurocognitive disorder, [2] encompasses several types of dementia involving the progressive degeneration of the brain's frontal and temporal lobes. [3] Men and women appear to be equally affected. [1]
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 ...
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 CBGTC loop has been implicated in many diseases. For example, in Parkinson's disease, degeneration of dopaminergic neurons leading to decreased activity of the excitatory pathway is thought to result in hypokinesia, [15] and in Huntington's disease, degeneration of GABAergic neurons driving the inhibitory pathway is thought to result in the jerky body movements. [2]
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]
Cannabidiorcol (CBDO, CBD-C1, O-1821) is a phytocannabinoid found naturally in Cannabis in trace concentrations. It is related to cannabidiol , with the pentyl side chain shortened to a methyl group.
