Q

headache dx/tx

A

if concerns for pathology, MRI first line within 2-4 weeks. tx: NSAIDs first line for acute treatment. if abortive meds for migraines, sumatriptan/zolmitriptan taken at onset. don’t use >3x/week. prophylactic when severe 2-4x/month or tension or migraine with functional disability. meds: B-blockers, antidepressants, anticonvulsants, CCBs. can do magnesium, coenzyme Q10, riboflavin, butterbur, omega3, migraleif. refer suspected pathological headaches

Q

Epilepsy

A

recurrent unprovoked seizures (event with abnormal electrical signal from cerebral cortex). can generalized or focal. single unprovoked with risk for future ones or 2 unprovoked more than 24hr apart or diagnosis of syndrome. staring spell can be triggered by 2-3 min hyperventilation.

Q

epilepsy dx

A

CBC, LFTs, glucose, LP if <6mo or with persistent neuro s/s; EEG, MRI after focal seizure or EEG abnormal or s/s ICP or >15min or <6mo, or new onset of focal neuro deficit. Diff: breath holding, inattentive staring, benign movements, self-stimulation, tantrums, syncope, migraine headaches, GERD, conversion disorder, metabolic problems, tumors, etc.

Q

Common epilepsy meds

A

Keppra (mood changes, headache, significant aggression or depression) lamotrigine (SJS, somnolence, headache, dizziness); oxcarbazepine for focal (hyponatremia, dizziness, ataxia, drowsy, SJS, blood cell count changes); topiramate (glaucoma, met. acidosis, paresthesia, weight loss, cognitive change); lacosamide (suicide, syncope, arrhythmia, dizzy, headache, ataxia); valproic acid (bone marrow suppression, weight gain, hair loss, liver toxicity, pancreatitis); ethosuximide for absence sz (blood cell changes, SJS, upset stomach, headache, weight gain); carbamazepine for focal (SJS, hypersensitivity, photosensitivity, tiredness); phenobarbital for neonatal or status (blood cell count changes, SJS, irreversible cognitive change, sedation, GI s/s)

Q

seizure med pointers

A

if GI effects, decrease dosage/increase frequency; first s/s of toxicity is sedation, changes in behavior, and changes in cognition and balance. some herbal products interfere with seizure control. taper if child can go 2 years without a seizure. leg prior to taper. most tapered over 6-8w. if return of sz, return to initial med dose. epilepsy resolved when 10 years seizure free and 5 without meds.

Q

keto diet

A

first line for GLUT1 transporter deficiency, or for intractable. high ratio of fats to protein plus carbohydrates. typical 4:1 ratio. prior to starting, r/o certain metabolic conditions. screen for growth and nutritional status. side effects: vitamin and mineral deficiency, abdominal pain, constipation or diarrhea, fatigue, slowed growth, renal stones.

Q

CP s/s

A

hypotonic < 6mo, then hypertonic. decreased head circumference, early head injury, persistent primitive reflexes, hand preference before 1 year of age, feeding issues, irritable or depressed, difficulty with movement, speech issues, asymmetric or abnormal deep tendon reflexes, ankle clonus,

17
Q

CP risk factors

A

maternal vaginal bleeding 6-9th months pregnancy; severe proteinuria or preeclampsia, antepartal hemorrhage/stroke/seizures, maternal hyperthyroid, maternal infection exposure; labor/delivery, fetal distress, SGA, low birth weight, preemie, multiple births, intracranial hemorrhage, meningitis, encephalitis, head trauma

18
Q

cp dx/tx

A

hammersmith neuro exam, GMFCS. MRI, chromosomal/metabolic studies, LP if sepsis suspected. CP is a central disorder. refer, educate, support, help with finances. manage nutrition, BM, dentistry, drooling, swallow study, respiratory infections, skin breakdown, antispasmodic med, botox, may need help for osteopenia, vision issues, may need surgeries
