Better Sleep Quality May Support Brain Function in People With Stroke, Diabetes and Heart Disease

Sleep plays an important role in memory consolidation, attention, learning and the maintenance of normal brain function.

People living with chronic conditions such as diabetes, heart disease and stroke may experience sleep disturbances due to pain, medication effects, breathing problems, anxiety or changes in neurological function.

Poor sleep can affect concentration, memory and the ability to perform everyday activities. It may also complicate the management of existing health conditions.

Research reported on 12 November examined the relationship between sleep quality and cognitive performance in people with type 2 diabetes, cardiovascular disease or a history of stroke.

The findings suggest that better sleep quality may be associated with improved cognitive function in these patient groups. The research adds to growing evidence that sleep should be considered an important component of long-term neurological and general healthcare.

However, an association does not prove that improving sleep alone will reverse cognitive impairment or prevent dementia. More research is required to determine which sleep interventions provide measurable benefits for different patient groups.

Patients with persistent insomnia, loud snoring, suspected sleep apnoea or excessive daytime sleepiness should discuss these symptoms with a healthcare professional.
