Symptoms and Signs of Hypersomnia

Doctor's Notes on Hypersomnia

Hypersomnia is a condition of recurrent episodes of excessive daytime sleepiness or prolonged nighttime sleep. Signs and symptoms include recurrent episodes of excessive daytime sleepiness or prolonged nighttime sleep, compelled to take naps during the day, no relief from napping, difficulty in waking up and/or feel disoriented. Other symptoms are anxiety, irritation, decreased energy, slowing of speech and thinking, loss of appetite, hallucinations and memory problems.

The underlying causes are not clear; some believe other sleep disorders may cause hypersomnia, others suggest tumors, head trauma or some injury to the central nervous system is responsible. Drug and alcohol abuse, medications, medical diseases like depression, epilepsy or obesity and genetics are linked to the underlying cause of hypersomnia according to some researchers.
