Central nervous system disease

Central nervous system diseases, also known as central nervous system disorders, are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS). These disorders may be caused by such things as infection, injury, blood clots, age related degeneration, cancer, autoimmune disfunction, and birth defects. The symptoms vary widely, as do the treatments. Central nervous system tumors are the most common forms of pediatric cancer. Brain tumors are the most frequent and have the highest mortality. Some disorders, such as substance addiction, autism, and ADHD may be regarded as CNS disorders, though the classifications are not without dispute. Every disease has different signs and symptoms. Some of them are persistent headache; pain in the face, back, arms, or legs; an inability to concentrate; loss of feeling; memory loss; loss of muscle strength; tremors; seizures; increased reflexes, spasticity, tics; paralysis; and slurred speech. One should seek medical attention if affected by these. Traumatic brain injury Any type of traumatic brain injury (TBI) or injury done to the spinal cord can result in a wide spectrum of disabilities in a person. Depending on the section of the brain or spinal cord that experiences the trauma, the outcome may be anticipated. List of central nervous system infections Infectious diseases are transmitted in several ways. Some of these infections may affect the brain or spinal cord directly. Generally, an infection is a disease that is caused by the invasion of a microorganism or virus. Degenerative spinal disorders involve a loss of function in the spine. Pressure on the spinal cord and nerves may be associated with herniation or disc displacement. Brain degeneration also causes central nervous system diseases (i.e. Alzheimer's, Parkinson's, and Huntington's diseases). Studies have shown that obese people may have severe degeneration in the brain due to loss of tissue affecting cognition.

Addiction

L'addiction, , ou assuétude, est l'envie répétée et irrépressible de faire ou de consommer quelque chose en dépit de la motivation et des efforts du sujet pour s'y soustraire. L'anglicisme addiction désigne tout attachement nocif à une substance ou à une activité. Le terme plus ancien d’assuétude est d'usage courant dans certaines régions de la francophonie, notamment au Québec. Dans d'autres régions, il est vieilli, mais reste parfois utilisé pour qualifier des dépendances faibles comme celle au chocolat.
