Can you name this sleep disorder?

Recommended Posts

Hi all;

My husband and I are totally mis-matched with our sleep disorders. I am 51 and have Delayed Sleep Phase Syndrome, diagnosed by 3 sleep clinics (whch means I am ready to go out and party at night). My husband, 61, I suspect, has Advanced Sleep Phase Syndrome. (see below). Which means he's up early and active in the mornings, naps, and is as useless after 8pm as I am before noon!

Ok, so we know all that. But what causes him to act DRUNK by 10pm? (He doesn't drink or do drugs or pills). Also, when he's driving after about 8pm, his reflexes slow way down to the point where he can hardly drive. He is in denial about this completely! And he gets so grumpy you can't talk to him. (Which, if he were to get drunk on a few beers, he is totally a happy drunk).

Does anyone know what aspect of ASPS having slurred speech is? Or is this a whole other sleep disorder, maybe? He won't go to a sleep clinic because, like I said, he insists "nothings wrong" with him.


What is advanced sleep phase syndrome?

Advanced sleep phase syndrome is a disorder in which the major sleep episode is advanced in relation to the desired clocktime, that results in symptoms of compelling evening sleepiness, an early sleep onset, and an awakening that is earlier than desired.

What are the symptoms?

Inability to stay awake until the desired bedtime or inability to remain asleep until the desired time of awakening

There is a phase advance of the major sleep episode in relation to the desired time for sleep

Symptoms are present for at least 3 months

When not required to remain awake until the later bedtime, patients will:

Have a habitual sleep period that is of normal quality and duration, with a sleep onset earlier than desired

Awaken spontaneously earlier than desired

Maintain stable entrainment to a 24-hour sleep-wake pattern

There is a chronic inability to stay awake in the evening or sleep later into the morning hours.

The major complaint may concern either the inability to stay awake in the evening, or early morning awakening insomnia, or both.

Unlike other sleep maintenance disorders, the early morning awakening occurs after a normal amount of undisturbed sleep.

Unlike other causes of excessive sleepiness, daytime school or work activities are not affected by sleepiness.

However, the evening activities are cut short by the need to retire much earlier than the social norm.

Typical sleep onset times are between 6 and 8 p.m., and no later than 9 p.m., and wake times between 1 and 3 a.m., and no later than 5 a.m. These sleep-onset and wake times occur despite the patient's best efforts to delay sleep to later hours.

How does this affect a person?

There can be negative personal or social consequences that are due to leaving activites in the early to mid-evening hours in order to go to sleep.

Attempts to delay sleep onset to a time later than usual may result in embarrassment due to falling asleep during social gatherings, or more seriously from drowsiness or falling asleep while driving in the evening.

Individuals with advanced sleep phase syndrome who attempt to work evening or night shifts would have difficulty staying awake during the evening and early morning hours.

If chronically forced to stay up later for social or vocational reasons, the early awakening aspect of the syndrome could lead to chronic sleep deprivation and daytime sleepiness or napping.

Who gets advanced sleep phase syndrome?

It is more likely to appear in the elderly.

How is it treated?

Advanced sleep phase syndrome is treated with chronotherapy or bright light therapy. Chronotherapy would involve a systematic advancement of bedtime until the desired bedtime is achieved. Bright light therapy would involve inducing a phase delay and the light exposure must be in the early evening. There is not a lot of data about the effectiveness of light therapy for ASPS.
