nervous system Pathology's Flashcards
type of senile dementia with characteristic lesions of the central cortex
Alzheimers disease
progressive, degenerative disease of motor neurons leading to muscle wasting and death: most common on 40-70 year old men
Amyotrophic lateral sclerosis (ALS)
AKA Lou Gehrigs disease
weakening and bulging of an artery; may leak and cause transient headaches and neck stiffness; if bursts it could be fatal
Aneurysm
Permanent, non progressive damage to motor areas of the brain before or during birth, symptoms often include spastic paralysis
cerebral palsy
buildup of arteriosclerotic lesions( thickened, hardened areas of reduced elasticity) blood clots or hemorrhage may lead to stroke
cerebrovascular disease
brain trauma
mild, moderate, or servere
confusion, headache, vomiting
concussion
group of disorders
progressive degeneration of neurons in the Brain leading to personality changes. loss of memory and diminished capabilities
dementia
inflammation of the brain
Encephalitis
inherited, progressive disorder causing uncontrolled muscular contractions; onset in 30’s and death within 25 years
Huntingtons disease
Inflammation of the meninges with symptoms of fever, headache, stiff neck, malaise, and photophobia
meningitis
loss of myelin sheath covering neurons and plaque formation in the CNS that decreases nerve conduction; muscle wasting; most common in women 20-40 years old; remission and relapse can occur
multiple sclerosis
chronic nervous disorder; degeneration of motor neurons of the mid-brain and decreases of a neurotransmitter; tremors, mask like expression and shuffling gait
lack of dopamine
Parkinson’s disease
abnormal neuron activity
range from minor moments of blankness to extreme physical convulsions
seizures
failure of Dorsal structures to fuse during development including the vertebra; the spinal cord or meninges may be exposed
lack of folic acid
spina bifida
severity dependent in location of the cord damage
decubitus ulcers; bed sores
spinal cord injuries
death or dysfunction of neurons from ischemia or hemorrhage; paralysis, paresis, aphasia; confusion
cerebrovascular accident
AKA; stroke
vascular disturbance in brain tissue; stroke like symptoms last less than 24 hours followed by complete recovery; slurred speech; often a warning of a major stroke
transient ischemic attack
AKA; mini stroke
Inflammation of the facial nerve (7th cranial nerve); unilateral pain, numbness and paralysis of face
bells palsy
palmar pain and numbness in first three digits
compression of median nerve
carpal tunnel syndrome
pain of loss of function of nerves as a result of chronic compression. tissues that can bind and impinge on nerves are the skin, fasciae, muscles, ligaments, and bones
compression syndromes
burning pain and rash in a dermatomal pattern
herpes zoster
AKA shingles
pain, numbness of tingling along the sciatic nerve
sciatica
an impingement of the brachial plexus often misdiagnosed as carpal tunnel syndrome
thoracic outlet syndrome
an impingement of the brachial plexus
whiplash
