Herpesviradaeherpes viruses 6 known herpes type viruses 1. herpes simplex virus 1 a. nongenital infections b. 90% of herpes encephalitis case are hsv-1 c. encephalitis occurs in roughly 2 per one million people per year, peak occurrence between 5-30 years old, over 50-30% to 70% are fatal, many are left with serious d. npsych finndings, children and young adults are more susceptible to encephalitis than older adults, can travel through cranial nerves-particularly olfactory, and trigeminal (may lie dormant for years and then spread through trigeminal),e. neuroanatomical effects: necrosis, edema, hemorrhageleads to swelling and possibly herniation (i.e.., coma and death as possibilities), preference for frontal and temporal lobeslesions seen of mri (increased signal intensity) and eeg, neuronscowdry a bodies, patient presents with fever and develops focal neurological signs, patient can have seizures, gustatory auras, can be aphasic, rapid detioration/confusion/coma and death can occur, tx. with acyclovir, case study. 2. herpes simplex virus 2 a. genital infections 3. herpes varicellazoster virus a. chicken pox b. shingles c. herpes encephalitis-rare 4. epstein-barr virus 5. cytomegalovirus-: 1/1000 infants have neurologic sequelae from cmv-typically effects fetal development (3-4 months of gestation) not as much as adults-only in adults that are susceptible to infectionhiv (1/3 of hiv) 90-100% of normal population has antibodies to virus, ives in uterine cervical mucosa, neuropsych: mr, seizures, low i.q.& hearing difficulties, usually diagnosed post mortem because features may be subclinical in nature and there are no specific neurological, neuropsychological features that are found with diseas. in adulthood pts. w/hiv and, cmv reported more confusion,disorientation, apathy than, hiv alone, also died earlier, difficult to distinguish effect of cmv and hiv in hiv dementianeuroanatomy-periventricular calcifications inclusion cowdry a, hydrocephalus, microcephaly 6. herpes virus 6does not cause problems in humans
