Excessive sleepiness in teenagers - What are the causes and what to do?

Adolescents and young adults (13–22 years of age) are often excessively sleepy.

This excessive sleepiness can have a profound negative effect on:

- school performance
- cognitive function
- mood
- increased incidence of automobile crashes

Excessive sleepiness - What are the causes?

The main reason adolescents don’t get enough sleep is that they simply don’t make enough time for it, because of early school hours, homework, part-time jobs, and other demands. The typical high school student falls asleep at 11 or later. One reason is that many teenagers cherish the late night as one of the few times they have all to themselves.

The “BEARS” screening is divided into 5 major sleep domains and provides a comprehensive screen for the major sleep disorders affecting children in the 2- to 18-year age range. Each sleep domain has a set of age-appropriate “trigger questions” for use in the clinical interview.

“BEARS”: A Sample Sleep History

B = Bedtime problems (Do you have any problems falling asleep at bedtime?)
E = Excessive daytime sleepiness (Do you feel sleepy a lot during the day? In school? While driving?)
A = Awakenings during the night (Do you wake up a lot at night?)
R = Regularity and duration of sleep (What time do you usually go to bed on school nights? Weekends? How much sleep do you usually get?)
S = Sleep-disordered breathing (Parent: Does your teenager snore loudly or nightly? Patient: Has anyone ever told you that you snore loudly at night?)

An algorithm can be used for diagnosing and treating sleep disorders. One sample assessment tool is shown below. Treatment should be directed at any potentially reversible process.



Excessive sleepiness - what to do?

- Adjust the lighting. As bedtime approaches, dim the lights. In the morning, expose your teen to bright light.

- Agree on a schedule, and stick to it. Tough as it may be, encourage your teen to go to bed and get up at the same time every day — even on weekends.

- Stop long naps. If your teen is drowsy during the day, a 30-minute nap after school might be refreshing. Be cautious, though. Too much daytime shut-eye might only make it harder to fall asleep at night.

- Set limits on electronic devices. Take the TV out of your teen's room, or keep it off at night. The same goes for your teen's cellphone, computer and other electronic devices.

- Relax. Encourage your teen to wind down at night with a warm shower, a book or other relaxing activities. Discourage stimulating activities — including vigorous exercise, loud music, video games, television, computer use and text messaging — an hour or two before bedtime.

- Limit the caffeine.

Presentation: Fructose drives hyperuricemia and uric acid then causes hypertension

The following presentation is by the nephrologist Joel Topf who writes the blog PBFluids.com. The subject is how fructose drives hyperuricemia and how uric acid then causes hypertension.

He used the slidecast feature on slideshare (http://www.slideshare.net/faqs/slidecast), so the slides have a full audio track.

Norepinephrine Causes Fewer Adverse Events Than Dopamine in the Treatment of Shock

Both dopamine and norepinephrine (Levophed) are recommended as first-line vasopressor agents in the treatment of shock. There is a continuing controversy about whether one agent is superior to the other.

Although there was no significant difference in the rate of death between patients with shock who were treated with dopamine as the first-line vasopressor agent and those who were treated with norepinephrine, the use of dopamine was associated with a greater number of adverse events.

Too much of a good thing? Excess fluoride in water supply causes dental

Too much of a good thing? Excess fluoride in water supply causes dental problems



For the first time in nearly 50 years, the government is recommending lowering the fluoride in drinking water. Officials say many Americans are getting too much fluoride and it's causing some kids to have "splotchy" teeth. The AP's Kelly Daschle reports.

The US health department is recommending that water supplies contain 0.7 milligrams of fluoride per liter of water, replacing the current recommended range of 0.7 to 1.2 milligrams.

Learn how much fluoride is in your tap water. Call your local water municipality because the level varies from city to city. If it's above 0.7 milligrams per liter, you could consider filtering your water.
