A transient ischemic attack (TIA), also known as a "mini-stroke," is a temporary disruption of blood flow to the brain that leads to sudden but short-lived neurological deficits. It is caused by a temporary blockage of a blood vessel, but unlike a stroke, it does not cause permanent brain damage and the symptoms usually subside within an hour. A TIA is considered a serious warning sign for a ... Continue reading
Transcranial direct current stimulation (tDCS) is a non-invasive procedure in which weak direct currents are conducted through the brain via electrodes on the scalp in order to modulate neural activity. It is mainly used to treat depression and chronic pain, such as fibromyalgia, but can also be used for stroke, migraine, and tinnitus. The method is considered effective ... Continue reading
Transcranial magnetic stimulation (TMS) TMS (transcranial magnetic stimulation) is a non-invasive procedure that uses magnetic fields to stimulate or inhibit nerve cells in the brain. In the treatment of epilepsy, TMS can be used to promote the brain's adaptability and alleviate symptoms, but it also carries risks, such as triggering an epileptic seizure, which ...

Tremor refers to a movement disorder characterized by involuntary, strictly rhythmic, and repetitive contractions of antagonistic muscle groups.
Trepanation is a medical procedure in which a hole is drilled into a bone, most commonly the skull, to relieve pressure, drain fluid, or provide access to the interior. While cranial trepanation is one of the oldest known surgical procedures (used to relieve pressure or drive out evil spirits), the term is now also used for procedures ... Continue reading
Triiodothyronine (T3) is an important thyroid hormone that controls metabolism and growth processes in the body. It is largely produced outside the thyroid gland from the hormone thyroxine (T4) and is the most biologically active form of thyroid hormone. Changes in T3 levels in the blood can indicate hyperthyroidism or hypothyroidism, which doctors diagnose by measuring the level of free triiodothyronine (fT3). Function and significance Metabolic regulation: T3 is essential for ... Continue reading
Tryptophan is an essential amino acid that the body cannot produce itself and must be obtained from food. It is an important precursor for the production of the neurotransmitters serotonin and melatonin, as well as vitamin B3 (niacin). Tryptophan is important for many vital processes, including regulating the sleep-wake cycle, influencing mood, and forming ... Continue reading
