Acute stage of HIV
few weeks after initial infection, flu like symptoms, virus multiplies and infects CD4+T cells
Dvpmt of antibodies in response to HIV infection
Symptomatic HIV infection
Toward end of chronic phase, individuals become symptomatic and have opportunistic infections
Crisis stage of HIV
Opportunistic infections more sevre. May have ADC (Aids dementia complex); unable to fight simple infections.
Forms in bone marrow cells that are precursors of red blood cells, platelets, and white blood cells
Forms in bone marrow cells that are designed to mature into lymphocytes
fast-growing, aggressive cancers that form blasts
Doesn't occur in blast cells, threfore is slow-growing and less aggressive.
Four stages to migraine
Prodrone, aura, headache, and resolution
Antiemetics (for nausea and vomiting), anti-inflamatory meds/opiates for pain, bx therapy, relaxation therapy, biofeedback
Most common headaches, feel like tightening of neck and scalp muscles. Exacberated by noise of uncomfortable environments; more common in women, feels like tight band around head.
Least common type of headache; felt on one side of head behind eye; more common in men
Lesions in brain and spinal cord related to demyelization. Cause unknown. Onset usually in young adults, disproportionally affects women.
Most common; relapses followed by months to years of remission w/no new signs of disease activity
(65%), progressive neurological decline between acute attacks without any definite periods of remission
(10-15%) Never have remission after initial sx. Progression of disability from onset, with no, or only occasional and minor remissions and improvements
Steady decline, but also suffer clear imposed attacks. Least common of subtypes.
Simple partial seizure
Focal disruption of brain activity, no loss of consciousness, may have changes in sensory perception, dizziness or tingling, involuntary jerking of body
Complex Partial seizure
Focal disruption in brain, altered level of consciousness adn decreased ability to interact with environment, non-puposeful repetitive mvmts, changed in mood and uncontrollable laughing or fear
Involves entire brain, staring (w/lack of awareness) and sometimes subtle body mvmts
Involved entire brain, jerking or twitching o limbs
Entire brain, associated with loss of muscle tone and results in sudden collapse
Grand Mal (tonic clonic)
Entire brain, loss of consciousness, stiffening, shaking/convulsing of entire body, sometimes loss of bladder control. May be followed by confusion, fatigue, and headache
Cervical/neck and arms
Thoraic/chest and arms
No morot or sensor function preserved in S4-S5
Prserved sensory, but not motor function below injury level and includes S4-S5 (incomplete)
Motor function preserved below level of injury and more than half of key muscles less than grade 3
