 Parkinson's | caused by loss of dopamine-producing brain cells causing progressive deterioration of nerve cells affecting part of brain that controls muscle movement. Loss of muscle function when there's not a enough dopamine & nerve cells can't transmit the message. |
| MS | chronic disease; a gradual loss of myelin sheaths. decrease in myelin, a result of the immune system's attack on myelin proteins, causes a significant reduction in the current of APs causing successive nodes 2 be excited slower; eventually decrease in overall impulse conduction |
| TBI | caused by a blow or jolt 2 head or a penetrating head injury that disrupts normal function of the brain; not all head injuries result in TBI; ranges from mild (concussion) 2 severe (loss of consciousness); people w/ TBI showed lower scores on motor control tests. |
| Huntington's | progressive degenerative disease affecting CNS, causing nerve cells in brain 2 stop functioning & waste away; affects muscle coordination & cognitive functions |
| Amyotrophic Lateral Sclerosis (Lou Gehrig's disease) | degeneration of upper motor neurons in medulla oblongata & lower motor neurons of spinal cord that control voluntary movement, results in muscle atrophy; nerve cells waste away or die & can't send messages 2 the muscles |
| cerebral palsy | caused by abnormalities or damage in parts of brain that control muscle movements. Permanently affects muscle control, posture, coordination, & also speech problems, hearing, vision, breathing, eating, learning disabilities, bladder & bowel control |
| symptoms of huntington's | uncontrolled movements, emotional disturbances & mental deterioration |
| symptoms of cerebral palsy | inability or difficulty smiling, rolling over, sitting, crawling, & walking; usually detected in infants |
| symptoms of TBI | Vary by extremity of injury. TBI may cause 1 of 5 abnormal states of consciousness: stupor, coma, persistent vegetative state, locked-in syndrome & brain death |
| symptoms of Lou Gehrig's | loss of muscular strength & coordination, twitching, weakness, atrophy in feet & hand muscles causing inability 2 move extremities; impaired speech, difficulty chewing, swallowing, & breathing; sometimes choking & drooling |
| symptoms of Parkinson's | tremors in hands, arms, legs, jaw, face which can decrease muscle tone; stiffness of limbs & trunk causing slow movement, postural instability, impaired balance & coordination; w/ progression: difficulty talking & walking |
| symptoms of MS | disruptions in gait, balance, & coordination, possible tremors, tingling & numbness; eventually paralysis or blindness |
