Hypersomnia is a condition where a person has trouble staying awake during daytime. People with hypersomnia can fall asleep any time. They have a lack of energy to perform activities, are unable to think clearly and may also suffer from sleep related problems. The causes include obesity, alcohol or drug abuse, head injury, genetic factor and sleep deprivation. Symptoms include irritation, anxiety, restlessness, slurred speech and memory difficulty.
