Local Area Networks. Local area networks (LANs) are used to connect networking devices that are in a very close geographic area, such as a floor of a building, a building itself, or a campus environment. Wide area networks (WANs) are used to connect LANs together.
Antidepressant medicines, which are usually used to treat depression, can be effective in preventing chronic tension headaches. Antidepressants have some pain-relieving properties and may reduce how often headaches occur and how long they last.
Tricyclic antidepressants are sometimes prescribed to treat various types of pain, including headache. Amitriptyline (Elavil, Endep) is the best studied for pain relief and the most often prescribed for migraine prevention: it's about 60% effective in thwarting such headaches. Other tricyclics used in migraine prevention include doxepin (Adapin, Sinequan), imipramine (Tofranil), and nortriptyline (Aventyl, Pamelor).
