Dementia is a symptom of several underlying conditions and brain disorders affecting memory, communication, and thinking is a part of Alzheimer’s disease and also Huntington’s disease and Parkinson’s disease.
A study conducted on 2,496 adults at least 51 years of age experiencing insomnia symptoms by American Academy of Sleep Medicine on nearly 2,500 adults in sleep journal predict that having trouble falling asleep is the main insomnia symptom led to cognitive impairment 14 years later.
Insomnia involves difficulty falling asleep or staying asleep, or regularly waking up earlier than desired, despite allowing enough time in bed for sleep and include symptoms like fatigue or sleepiness; feeling dissatisfied with sleep; having trouble concentrating; feeling depressed, anxious, or irritable; and having low motivation or energy.
‘Having trouble falling asleep predicts cognitive impairment in later life.’
“While there is growing evidence for a link between insomnia and cognitive impairment in older adults, it has been difficult to interpret the nature of these associations given how differently both insomnia and cognitive impairment can present across individuals,” said lead author Afsara Zaheed, a graduate student in clinical science within the department of psychology at the University of Michigan.
As sleep health and sleep behaviours are modifiable so regular screening for insomnia symptoms may help with tracking and identifying people with trouble falling asleep at risk for developing cognitive impairments later in life.
