About the Symptom
Sometimes people can have a decreased feeling of need for sleep. They may wake up throughout the night or having trouble falling asleep, but not feel sleepy the next day. Sometimes this can be an indication of a medical issue, such as Bipolar Disorder.

Possible Causes
Generally, I don't need sleep can be related to:
- Bipolar Disorder
A disorder marked by extreme and persistent shifts in mood that last for weeks to months, from periods of sustained depression to periods of elevated mood and euphoria. The precise cause is unclear, but genetic and environmental factors contribute.
- Sleep Disorder
Sleep disorders are conditions that affect the quality, timing, or duration of your sleep, impacting your ability to function when you're awake. There are many types of sleep disorders, including disturbances in sleep quality or quantity, excessive daytime sleepiness, abnormal behaviors during sleep, sleep disorders related to mental disorders, and more.
- Alzheimer's Disease
Alzheimer's disease is the most common cause of dementia. The brain shrinks, affecting memory and behavior. Symptoms worsen over time and can interfere with daily life. Increasing age raises the risk for Alzheimer dementia.
