Marijuana is a psychoactive sedative drug and is derived from the hemp plant, Cannabis sativa. Its leaves and buds can be smoked, taken in food, brewed in tea or taken … Continue Reading Neuroimaging shows that marijuana users have low blood flow to the brain.
Study shows that structure of toxic tau aggregates determines type of dementia, and rate of progression.
Recent efforts to develop a treatment for Alzheimer’s disease and other dementias have focused heavily on removing toxic tau proteins from the brain. The tau protein is known to bind … Continue Reading Study shows that structure of toxic tau aggregates determines type of dementia, and rate of progression.
It is known that Alzheimer’s disease is more common in African-Americans than Caucasians, however, the Alzheimer’s disease genetic risk profile for African-Americans is poorly understood. While more than 20 genes have … Continue Reading Study identifies 2 new genes responsible for Alzheimer’s disease among African-Americans.
Alzheimer’s disease is a neurodegenerative disorder characterized by progressive memory loss and cognitive dysfunction. It affects more than 30 million people worldwide, including an estimated 5.4 million Americans. One in … Continue Reading Dysfunction in neuronal transport mechanism linked to Alzheimer’s disease.
Alzheimer’s disease (AD) is characterized by cognitive decline, alteration of synaptic transmission, and neuronal death brought on by accumulation of neurofibrillary tangles in neurons and amyloid beta in the brain. … Continue Reading Study shows that vesicles appear to also contribute to Alzheimer’s disease.
Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles. Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.
For decades, scientists have known that people with two copies of a gene called apolipoprotein E4, or ApoE4, are much more likely to have Alzheimer’s disease at age 65 than … Continue Reading Study shows why people with the ApoE4 gene are more susceptible to Alzheimer’s disease.
The CDC estimates that more than 1.3 million Americans visit an emergency department each year because of a TBI-related injury. The late effects of TBI are of great interest, however, … Continue Reading Largest ever study identifies link between TBI and Parkinson’s, but not Alzheimer’s.
Alzheimer’s disease (AD) is common and highly heritable with many gene variants associated with it. However, the genetic risk for AD have not been clearly delineated, with the stage of … Continue Reading Study identifies a genetic risk score for Alzheimer’s disease in young adults.
Alzheimer’s disease is a devastating and progressive neurodegenerative disease affecting approximately 5.3 million people in the United States, including almost half of the population at 85 years and older. Microscopic hallmarks … Continue Reading New blood test detects early Alzheimer’s in large-scale study with unprecedented sensitivity.
It is known that one of the earliest sites of Alzheimer’s disease pathology is the hippocampus, a brain structure critical for the learning and memory processes that falter early in Alzheimer’s … Continue Reading Study shows how Alzheimer’s risk gene disrupts memory replay.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
