Pediatric Neuro Pathologies Flashcards
Cerebral Palsy Etiology
can occur before/during birth 2nd to lack of O2/maternal infection/ drug or alcohol abuse/ placental abnormalities/ toxemia/ prolonged labor/ prematurity/ Rh incompatibility
may also be due to meningitis, CVA, seizures, or brain injury
Cerebral Palsy Signs/Symptoms
mild-severe loss of control w/ profound mental retardation
All pts- abnormal muscle tone, imparied modulation of movement, presence of abnormal reflexes, impaired mobility
Cerebral Palsy Primary Motor Patterns
Spastic: indicates lesion in cerebral motor cortex- upper motor neuron damage
Athetoid: indicates lesion involving basal ganglia (cerebellar and cerebellum pathways)
Cerebral Palsy Distribution of Involvement
Monoplegia: one extremity
Diplegia: bilateral LE involvement (UE may still be affected)
Hemiplegia: unilateral involvement of UE and LE
Quadriplegia: involvement of entire body
Cerebral Palsy Treatment
Ongoing family/caregiver education Normalization of tone Stretch/Strengthen Reaching developmental milestones Positioning WB activities Mobility Skills Splinting/ assistive devices/ specialized seating may also be required Surgical intervention may be required for orthopedic management/ reduction of spasticity
Downs Syndrome Etiology
incomplete cell division of 21st pair of chromosomes (aka Trisomy 21)
risks= advanced maternal age
Downs Syndrome Signs/Symptoms
Mental retardation, hyoptonia, joint hypermobility, flattened nasal bridge, narrow eyelids w/ epicanthal folds, small mouth, feeding impairments, flat feet, scoliosis, congenital heart disease, visual/hearing loss
Downs Syndrome Treatment
Emphasize exercise/fitness, stability, maximized respiratory function, education for caregivers
Surgical intervention may be needed for cardiac abnormalities
Duchenne Muscular Dystrophy Etiology
inheritance of X-linked recessive trait- results in absence of gene required to produce muscle proteins (dystrophin & nebulin) causing weak cell membranes, destroyed myofibrils, lost muscle contractility
Fat/connective tissue replace muscle, death occurs from cardiopulmonary failure before age 25
Duchenne Muscular Dystrophy Signs/Symptoms
characteristics manifest between 2-5 yrs old
Progressive weakness, disinterest in running, falling, toe-walking, excessive lordosis, pseudohypertrophy of muscle groups
Duchenne Muscular Dystrophy Treatment
focus on family/caregiver education, respiratory function, submaximal exercise, mobility skills, splinting, orthotics, adaptive equipment
Meds= immunosuppressants, steroids, surgery for orthopedic impairment
Spina Bifida Occulta Etiology
impairment & non-fusion of spinous process of vertebrae, spinal cord & meninges remain intact- usually no associated disability
Spina Bifida Meningocele Etiology
herniation of meninges and cerebrospinal fluid into a sac that protrudes through the vertebral defect- spinal cord remains in canal
Spina Bifida Myelomeningocele Etiology
severe form characterized by herniation of meninges, cerebrospinal fluid and spinal cord extending through defect in vertebrae- cyst may/may not be covered by skin
Spina Bifida Signs/Symptoms
motor loss below level of defect, sensory deficits, hydrocephalus, osteoporosis, clubfoot, scoliosis, latex allergy, bowel/bladder dysfunction, learning disabilities
