Data from the Baltimore Longitudinal Study on Aging, begun in 1958, has revealed that seniors with hearing loss are significantly more likely to develop dementia than those who retain their hearing.
A study involving 360 patients with degenerative dementia (109 people with dementia with Lewy bodies (DLB) and 251 with Alzheimer's) and 149 matched controls, has found that 48% of those with DLB had previously suffered from adult ADHD.
Research into the link, if any, between cholesterol and dementia, has been somewhat contradictory. A very long-running Swedish study may explain why.
A study involving 68 healthy older adults (65-85) has compared brain activity among four groups, determined whether or not they carry the Alzheimer’s gene ApoE4 and whether their physical activity is reported to be high or low.
Clinical records of 211 patients diagnosed with probable Alzheimer's disease have revealed that those who have spoken two or more languages consistently over many years experienced a delay in the onset of their symptoms by as much as five years.
Data from 21,123 people, surveyed between 1978 and 1985 when in their 50s and tracked for dementia from 1994 to 2008, has revealed that those who smoked more than two packs per day in middle age had more than twice the risk of developing dementia, both Alzheimer's and vascular dementia, compared
A seven-year study involving 271 Finns aged 65-79 has revealed that increases in the level of homocysteine in the blood were associated with increasing risk of developing Alzheimer’s (each micromolar increase in the concentration of homocysteine increased the risk of Alzheimer's by 16%), while in
A Chinese study involving 153 older men (55+; average age 72), of whom 47 had mild cognitive impairment, has found that 10 of those in the MCI group developed probable Alzheimer's disease within a year.
Carriers of the so-called ‘Alzheimer’s gene’ (apoE4) comprise 65% of all Alzheimer's cases. A new study helps us understand why that’s true. Genetically engineered mice reveal that apoE4 is associated with the loss of GABAergic interneurons in the hippocampus.
Confirming earlier research, a study involving 257 older adults (average age 75) has found that a two-minute questionnaire filled out by a close friend or family member is more accurate that standard cognitive tests in detecting early signs of Alzheimer’s.
