Modafinil is indicated for the management of excessive daytime sleepiness associated with narcolepsy. The FDA has approved its use to improve wakefulness in patients with excessive sleepiness associated with obstructive sleep apnea/hypopnea syndrome and shift-work sleep disorder. Although modafinil improves measures of sleepiness, it does not normalize them because it does not correct the basic underlying cause. Therefore, treatment may be required for an indefinite period.

Vitamin E plays a role in the control of brain prostaglandin synthesis, regulation of nucleic acid synthesis, and gene expression. Neurologic and muscle dysfunction due to vitamin E deficiency may result from lack of antioxidant protection in susceptible tissues. Vitamin E has some therapeutic effect in a number of neurologic disorders where its deficiency has been demonstrated as well as a neuroprotective effect in some neurodegenerative disorders.

Stenosis of the lumbar spinal canal is most commonly associated with multilevel degenerative spine disease, although commonly worst at the L4-5 level. Neurogenic claudication is classically described as a poorly localized sense of discomfort and aching pain in the lower back, buttocks, and legs, precipitated by walking and relieved by sitting. Patients may experience numbness or deadness of the limbs, paresthesias, or subjective weakness that is usually bilateral and asymmetric.

Nutrition plays an important role in the development and function of the nervous system. These factors include carbohydrates such as glucose, proteins, amino acids (precursors of nucleic acids), and vitamins and minerals, which enter the brain through the blood-brain barrier. Neurologic disorders due to malnutrition may be treatable.

Drug-induced seizures can occur as an adverse effect of drugs from different pharmacological categories, and have no clinical features to differentiate them from idiopathic epileptic seizures. Most resolve after discontinuation of the offending drug. Use of drugs known to cause seizures should be avoided in patients with predisposition to seizures.
