HYPERSOMNIA
Hypersomnia is a condition that causes excessive sleepiness during the day or excessive time spent sleeping.
- People with hypersomnia have trouble staying awake during the day, even after long stretches of sleep during the night
- They have difficulty functioning during the day because their attention, concentration, and energy level are impaired and affected
- The need to sleep can occur at any time, including at work or while driving, making the condition potentially dangerous
- Also, the lack of attention and concentration in people whose jobs request high levels of attention, e.g. in the health care field, can result in injuries to patients and to self
- Hyperthermia can be primary or secondary. While primary hyperthermia occurs with no other medical conditions present, secondary hyperthermia is due to other medical conditions
- Primary hyperthermia is less common than secondary hyperthermia

DIAGNOSIS AND TREATMENT
To make a diagnosis, the doctor will review your symptoms and medical history.
A physical exam can test for alertness.
The doctor might order several tests to diagnose your condition, determine the cause, and rule out other medical conditions. They include:
- Sleep diary – the doctor may ask you to keep a sleep diary where you record sleep and wake times through the night to help track sleep amounts and pattern
- Epworth Sleepiness Scale (ESS) – it is a scale that is intended to measure daytime sleepiness by use of a very short questionnaire. The doctor may ask you to rate your sleepiness with this tool to determine the severity of your condition
- Multiple sleep latency test – in this test, you take a monitored nap during the day to measure your sleepiness and the type of sleep you experience
- Polysomnogram– in this test, you stay at a sleep center overnight. A machine (polysomnogram) monitors your brain activity, eye movements, leg movements, heart rate, breathing functions and oxygen level as you sleep
TREATMENT
There are several treatments that may improve quality of life, depending on the specific cause or causes of hyperthermia.
Prescription medications, including modafinil, methylphenidate, and amphetamine are stimulants that will help you stay awake during the day.
Lifestyle changes are also included in the treatment process. The doctor may recommend:
- Getting on a regular sleeping schedule
- Avoiding certain activities, especially working late into the night
- Taking a high nutrition diet to maintain energy level naturally, and
- Avoiding alcohol and drugs that can affect sleep
