Sleep plays an important role in our physical and mental health. Insufficient or poor quality sleep is linked to an increase risk of heart disease, high blood pressure, diabetes, weight gain and stroke.

Dementia and sleep disorders share a close relationship. Dementia patient tends to experience poor sleep pattern on a regular basis. They exhibit the symptoms of sleep apnea or temporay loss of breath during sleep.

Dementia can affect the body clock. People with dementia have a sleep pattern that is quite different from normal people. They have difficulty sleeping through the night and are often tired and sleepy during the day. This could be due to how they perceive the world.

There are many possible causes of these sleep changes. The way the brain controls sleep may have changed. They may be in pain which affects their sleep. The surrounding environment also plays a part in your sleep. Noise, heat, lights or mattress may be the contributing factors.

During the day, make sure they stay active. Have more outdoor activities to expose them to sunlight. Engage and communicate with them more often. Short naps may be helpful if they look tired.

During the night, the sleep room should be dark and quiet. Often people with dementia wake up and think it is morning if there is light. Experts believe that people with dementia get disturbed by  noise easily.
