Several neurodegenerative disorders are associated with oxidative stress that is manifested by lipid peroxidation, protein oxidation and other markers. Included in these disorders in which oxidative stress is thought to play an important role in their pathogenesis are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tardive dyskinesia, Huntington's disease (HD), and multiple sclerosis. This review presents some of the chemistry of vitamin E as an antioxidant and summarizes studies in which vitamin E has been employed in these disorders and models thereof.

The authors provide an extensive review of new data related to the role of glutamate in CNS disorders, describing new aspects in glutamate and glutamatergic receptors-NMDA receptors, NR2B-selective antagonists, non-NMDA ionotropic glutamate receptors, N-acetylaspartylglutamate, and glutamate and glycine transporters. New findings in animal models and in human diseases-stroke, traumatic brain injury, Alzheimer's, Parkinson's and Huntington's diseases, tardive dyskinesia, ALS, olivopontcerebellar degeneration, AIDS, allergic encephalomyelitis, epilepsy, anxiety, depression, schizophrenia, liver disease, aminoglycoside antibiotic-induced hearing loss, hemiplegia, chronic pain and drug tolerance and abuse-are presented. Finally, the authors cite the progress achieved in the development of agents that interact with the glutamatergic system: NMDA channel blockers, competitive NMDA receptor antagonists, NR2B-selective antagonists, glutamate release inhibitors, glycineB antagonists, AMPA and kainate receptor antagonists, AMPA receptor-positive modulators and agents that act by modifying endogenous kynurenic acid metabolism.

This article concludes the series on cranial nerves, with review of the final four (IX-XII). To summarize briefly, the most important and common syndrome caused by a disorder of the glossopharyngeal nerve (craniel nerve IX) is glossopharyngeal neuralgia. Also, swallowing function occasionally is compromised in a rare but disabling form of tardive dyskinesia called tardive dystonia, because the upper motor portion of the glossopharyngel nerve projects to the basal ganglia and can be affected by lesions in the basal ganglia. Vagus nerve funtion (craniel nerve X) can be compromised in schizophrenia, bulimia, obesity, and major depression. A cervical lesion to the nerve roots of the spinal accessory nerve (craniel nerve XI) can cause a cervical dystonia, which sometimes is misdiagnosed as a dyskinesia related to neuroleptic use. Finally, unilateral hypoglossal (craniel nerve XII) nerve palsy is one of the most common mononeuropathies caused by brain metastases. Supranuclear lesions of cranial nerve XII are involved in pseudobulbar palsy and ALS, and lower motor neuron lesions of cranial nerve XII can also be present in bulbar palsy and in ALS patients who also have lower motor neuron involvement. This article reviews these and other syndromes related to cranial nerves IX through XII that might be seen by psychiatry.

Much attention has been devoted to neurodegenerative diseases involving redox processes. This review comprises an update involving redox processes reported in the considerable literature in recent years. The mechanism involves reactive oxygen species and oxidative stress, usually in the brain. There are many examples including Parkinson's, Huntington's, Alzheimer's, prions, Down's syndrome, ataxia, multiple sclerosis, Creutzfeldt-Jacob disease, amyotrophic lateral sclerosis, schizophrenia, and Tardive Dyskinesia. Evidence indicates a protective role for antioxidants, which may have clinical implications. A multifaceted approach to mode of action appears reasonable.

Vitamin E (alpha-and gamma-tocopherol) may slow the progression of a number of major degenerative diseases of the nervous system that appear to be significantly worsened by oxidative stress. The effects of vitamin E on excitoxicity in cultured neurones is considered, together with ataxia due to vitamin E deficiency (AVED) arising from abetalipoproteinaemia, cholestatic liver disease, cystic fibrosis, short bowel syndrome, total parenteral nutrition, diabetic peripheral neuropathy and familial isolated vitamin E (FIVE) deficiency. Selenium deficiency in Keshan disease is also described in relation to the cardiomyopathy seen in Friedreich's ataxia. Evidence for any beneficial effects of vitamin E upon the course of Friedreich's ataxia, tardive dyskinesia, amyotrophic lateral sclerosis (motor neurone disease), Parkinson's disease, Alzheimer's disease, and Huntington's disease is examined. The application of vitamin E derivatives as protective agents in posttraumatic injury to the nervous system (stroke, head and spinal cord injury and haemorrhage) is discussed.
