Progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS), two atypical parkinsonian syndromes, may be twice as common as previously believed, researchers report.
Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia.
Researchers report senescent, or Zombie, cells accumulate in certain neurons prior to cognitive loss. By preventing accumulation of these cells, researchers were able to diminish apoptosis, memory loss and tau aggregation.
The findings reported in a new study could help improve the diagnosis and develop new treatments for neurodegenerative diseases such as Alzheimer's and Parkinson's.
A new study uncovers unique changes in DNA structure in genes important to neuronal function in relatives with early onset, familial Alzheimer's disease.
The same gene mutations linked to inherited, early-onset Alzheimer’s disease have been found in people with the more common late-onset...
