• Systemic lupus erythematosus: chronic autoimmune disease that can be fatal, though with recent medical advances, fatalities are becoming increasingly rare.
• Temporal lobe epilepsy: A condition which is characterized by complex partial seizures
• Tolterodine toxicity: The toxic reaction of the body to the substance, possibly via allergic reaction or overdose.
• Tranquilizer addiction: An uncontrollable desire to use tranquilizers on a regular basis. Tranquilizers are often prescribed for the treatment of anxiety and sleeping problems but chronic use can lead to dependence on the drug. Frequent use leads to an increased tolerance to the drug so higher and higher doses are required to achieve the desired euphoric feeling.
• Trypanosomiasis:
• Uremic encephalopathy: occurs due to build up of toxins which are normally cleared by the kidneys
• Variant Creutzfeldt-Jakob disease: The bovine spongiform encephalopathy affects cattle but the variant form can infect humans. Human infection can occur by consuming infected cattle products, especially the brain and other central nervous system tissues.
• Variegate porphyria: A rare metabolic disorder characterized by a deficiency of a certain enzyme which results in a build-up in the body of porphyrins or their precursors. This form of hepatic porphyria causes the sufferer to have acute attacks as well as skin sensitivity.
• Velocardiofacial syndrome: A genetic disorder which can present with a wide range of phenotypic manifestations which has lead to a number of different names being assigned to the various presentations e.g. DiGeorge Syndrome and Cayler Anomaly Face Syndrome. There are nearly 200 different symptoms that can occur and the severity of the condition is also highly variable depending on the nature and severity of the symptoms that are present.
• West African Trypanosomiasis: West African sleeping sickness from the tsetse fly
