While 40% of people with primary progressive aphasia have underlying Alzheimer's disease, a new study suggests they may not develop the memory problems associated with Alzheimer's. Read More
For carriers of the Parkinson's related LRRK2 gene, coffee consumption can help lower the risk of developing symptoms of the disease. Read More
Researchers identified five unapproved drugs in dangerous combinations and doses in over-the-counter cognitive enhancement drugs. Side effects of the unapproved drugs include increases and decreases in blood pressure, agitation, and sedation. Read More
A genetic variation that alters the metabolism of glutathione may be responsible for cognitive decline in people who do not have other associated biomarkers, a new study reports. Read More
Anticholinergic medications, commonly used for conditions including allergies, high blood pressure, Parkinson's disease, and motion sickness, have been linked to an increased risk of cognitive decline and memory problems, especially in those with genetic risk factors for Alzheimer's disease.

Eating a diet rich in vegetables and nuts during middle age is linked to fewer symptoms that may precede Parkinson's disease. Read More
Sleep disturbances may be an outcome of Alzheimer's in those with a genetic predisposition, but not a cause of dementia. Those with genetic risk factors for Alzheimer's tend to have shorter sleep durations and are more likely to be early risers but are less likely to suffer from insomnia. Read More
Twice daily vitamin D supplementation reduces symptoms of vertigo for those suffering BPPV. Read More
People who experience dizziness when standing face an increased risk of developing dementia, a new study reports. The increased risk appears to only apply to those who experience a drop in their systolic blood pressure. Those with systolic orthostatic hypotension were 40% more likely to develop dementia than those who did not suffer from the condition. Read More
22% of study participants with severe gum disease developed dementia, and 23% diagnosed with mild cognitive impairment suffered extreme tooth loss. Only 14% of those with healthy gums were later diagnosed with the neurodegenerative disorder. The findings add further evidence for the link between dental hygiene and dementia. Read More
Eating a diet rich in omega-3 fatty acids appears to have a positive effect on brain health in older women who live in areas with high levels of air pollution. Women with lower levels of omega-3 fatty acids in their blood had more brain shrinkage, specifically in the hippocampus than women with higher levels of omega-3. Read More
A new blood test can help predict which patients with multiple sclerosis will see a decline in their condition over 12 months. The test looks for a biomarker called neurofilament light chain, a protein that can be detected as nerve cells die. People with higher levels of the protein were 40-70% more likely to experience worsening symptoms over a year than those with lower levels. Read More
