Lifestyle Effects on Memory & Cognition

Latest news

  • The connection between sleep apnea and depression may lie in a problem with autobiographical memory.

Obstructive sleep apnea (OSA) occurs when a person's breathing is interrupted during sleep.

People with OSA are known to suffer memory problems and also have higher rates of depression.

  • Getting a good night’s sleep is given greater importance with the discovery that sleep deprivation appears to rapidly increase the spread of tau tangles.

Poor sleep has been associated with the development of Alzheimer's disease, and this has been thought to be in part because the protein amyloid beta increases with sleep deprivation. A new study explains more.

  • Older people who spend less time in slow-wave sleep (deep sleep) have higher levels of the Alzheimer’s brain protein tau.

Poor sleep has been associated with Alzheimer's disease risk, but a new study suggests a specific aspect of sleep is important.

  • A large study indicates that lifestyle changes, together with advice and support for managing vascular health, can help prevent cognitive decline even in carriers of the Alzheimer's gene.

A Finnish study involving over 1000 older adults suggests that a counselling program can prevent cognitive decline even among those with the Alzheimer’s gene.

  • A study of nearly half a million people has revealed that muscular strength is associated with brain health and cognitive performance, including among schizophrenics.

A British study using data from 475,397 participants has shown that, on average, stronger people performed better across every test of brain functioning used.

  • While handgrip strength has been linked to dementia risk in the elderly, a new study indicates that less impaired or fragile older adults need upper and lower body strength tests — but that these, too, are correlated with cognitive function.

A Finnish study involving 338 older adults (average age 66) has found that greater muscle strength is associated with better cognitive function.

  • Brain scans of healthy young adults found that higher aerobic fitness was associated with greater hippocampal elasticity, which was a better predictor of cognitive performance than hippocampal volume.

A new MRI technique has revealed that it is the structural integrity of the

  • A review of research has confirmed the benefits of at least moderate exercise to fight age-related cognitive decline, with different benefits for aerobic exercise and strength training.

A review of 39 studies investigating the effect of exercise on cognition in older adults (50+) confirms that physical exercise does indeed improve cognitive function in the over 50s, regardless of their cognitive status.

  • A review of research has concluded that even a single bout of physical activity can have significant positive effects on people's mood and cognitive functions.

An extensive review of research looking at the effects of a single bout of exercise has concluded that:

  • Regular exercise has been found to reduce brain shrinkage in those with mild cognitive impairment.

A study involving 35 adults with
