There are several types of sleeping disorders but primary sleep disorder is broken down into two main categories.
Primary sleep disorders are not caused by other mental disorders, substance abuse, prescription usage or other medical conditions and that is why they are classified differently that others.
Dyssomnias This is a category of primary sleep disorder that is due to the patient suffering from varied amounts of restful sleep and the amount of time he spends in a restful sleep mode.
Insomnia is included in this category.
Insomnia is due to physical or psychological disturbances that arouse the patient during his regular sleeping hours.
The problem with insomnia is that the patient can become anxious about his inability to sleep, causing more nights filled with no rest.
Not only are people with insomnia unable to sleep well, their routine and even their bed becomes an object of this anxiety, creating more problems as time passes.
This type of disorder can be seen in young adults and also affects middle-aged patients.
Hypersomnia is another disorder in this category that can be characterized by the patient feeling sleepy during the day or during activities that normally require alertness.
Even if the person seems to be getting a full night's rest, he will often sleep for several hours during the day.
This patient is frequently hard to arouse and may display moments of disorientation and anger when trying to wake up.
This disorder is generally seen in males between the ages of 15 and 30 years.
This disorder is sometimes referred to as sleep drunkenness and can cause a great deal of stress in the patient suffering with this problem.
Parasomnias This disorder is categorized by the inability to have a smooth transition during waking and sleeping that are a part of normal sleep.
This can include sleepwalking, nightmares, and even night terrors that wake the patient during restful sleep and does not allow him to fall asleep after the incident has occurred.
Night terrors are typically the result of a nightmare that can not be recalled and the patient usually wakes up crying or screaming.
Nightmares are bad dreams that cause a patient to wake up feeling frightened or alarmed.
Sleepwalking is different in that the patient can walk around and perform simple activities while still being asleep.
Children often sleep walk and although it may be hard for parents to get used to these, children can usually grow out of it and regain a healthy sleep filled night.
