In healthy older adults, depression and cortical amyloid may be associated with early changes in cognition. The findings provide an additional biomarker for Alzheimer's disease.
Hippocampal neurogenesis continues to occur well into old age, and in those with Alzheimer's disease. Researchers found evidence of neurogenesis in people up to the age of 99. While neurogenesis continues to occur in those with Alzheimer's disease, it is significantly reduced compared to those who have normal cognitive function.
Researchers report abnormal development of the prefrontal cortex and maternal stress may lead to brain activity and cognitive impairments linked to psychiatric diseases such as Schizophrenia and bipolar disorder.
Older people may rely more on schematic memory, resulting in a difficulty distinguishing between a memory of a real event and a false memory.
Researchers develop a method to decrypt the brain while it sleeps to reveal hidden memories.
A new study reports people with major depression had 32 percent more FGF9 in a key area of their brain than those without depression.
