Axon myelination is significantly disrupted in patients with Alzheimer's disease. Researchers also found brain cells of men and women vary significantly in how their genes respond to the neurodegenerative disease.
Six months of aerobic exercise intervention was associated with cognitive improvements and cerebrovascular regulation. Older people who embarked on the aerobic exercise program had, on average, a 5.7% improvement on tests of executive function and verbal fluency similar to that of a person five years younger.
Contrary to popular belief, taking a low-dose of aspirin daily does not reduce the risk of developing mild cognitive impairment (MCI). Researchers found no difference between older people who took aspirin and those who took a placebo in the risk of developing MCI, dementia, or Alzheimer's disease.
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.
Older adults who eat a diet rich in vegetables, fruits, fish and nuts have greater brain volume, a new study reveals. Researchers say diet can influence brain shrinkage and the development of neurodegenerative diseases as we age.
People with bipolar disorder have higher incidences of Parkinson's disease than those without the psychiatric condition. Manic and depressive episodes were associated with an elevated risk of developing Parkinson's disease.
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.
