Hypersomnia: What causes it?

On the website MayoClinic.com, they explained the term:  Hypersomnia as characterized by recurrent episodes of excessive daytime sleepiness or prolonged nighttime sleep.  People with hypersomnia are compelled to nap repeatedly during the day, often at inappropriate times, despite getting adequate sleep.  Hypersomnia has many potential causes, including:

In addition, certain medical conditions can contribute to hypersomnia, including multiple sclerosis, depression, encephalitis and epilepsy.  Sometimes the cause of hypersomnia can’t be determined.  Doctors refer to this as idiopathic hypersomnia.

Treatment depends on the underlying cause of hypersomnia.

    I know exactly what you mean! Some days, my alarms (I have 3) goes off for hours and I sleep straight through it. My boyfriend even bought me the alarm clock for people who have hearing impairments. It would shake the bed violently when it went off. However, it met an unfortunate end when I slept through it for about 2 hours and the connection between the vibrating disk and the clock began to smoke.

    I was long convinced that my frequest and random passing out on the couch (once with my dinner still in my lap) was due to graduate school sleep deprivation. However, that is long over and I get pleanty of sleep at night – yet it still happens off and on. My mood is pretty consistent and I don’t have other signs of depression either.

    Of course, while Depression is often a favorite diagnosis for so many ills, one should always consult an MD prior to going for a psychological diagnosis in regard to issues that more often have a physical component (such as hypersomnia). This is a good practice, since some issues that appear psychological can be easily addressed physical issues or more nepharious ones that require early detection (i.e., brain tumors, cadiovascular issues, and so on). The body and mind are connected intimately, but addressing the physical possibilities first is a more concrete way of addressing the problem. It gives a good place to start.

    I will take my own advice.

    I normally go to bed about 12 am. I wake up about 7 am but have no will to get up. I watch some TV while in bed. Then I fall sleep, in spite of loud TV, and wake up about 12 PM. I have no idea how time went bye. It’s as if I fainted or something. I hate it so much because it is such a waste of time. I’d rather get up and do something constructive or go to the beach and walk (I’m retired and live in San Diego where we enjoy great weather year around!)

    This has been going on for about 10 years. I broke this cycle for about a year by forcing myself to get up and this was the happiest time in my life. I was so proud of myself and very excited. Unfortunately I fell back in the trap again. The problem is that I don’t seem to have any will power. I don’t feel depressed and my mood is pretty steady. I’m reasonably happy and well adjusted and not gloomy at all so I reject the notion that my oversleeping is due to depression. Any clues will be greatly appreciated. Allen

      I’m so happy this worked for you. I rarely get a good night’s sleep; the dog sleeps better than me and she sleeps during the day also. If it wasn’t for meds, I’d be up watching re-runs of “Laverne & Shirley” at 3:00 a.m.
