Pharmacological treatments have to be administered carefully. Some medication is highly addictive and the resulting withdrawal syndromes cause even more sleep disturbances, e.g. Insomnia. Possible medications are Zopiclone and lorazepam, which have been proven effective in people with TBI. Also Benzodiazepine hypnotics, Benzodiazepine-receptor antagonists, antidepressants, psychostimulants can be administered, especially in patients with insomnia. Some studies have shown negative effects of hypnotics, such as an increased risk of dementia. In patients with hypersomnia, Modafinil, Armodafinil, Methylphenidate and amphetamines are often used as a treatment for day time sleepiness. Medication should always be prescribed by an expert to make sure that the correct medicament is taken in an appropriate dose.
