epilepsy
impaired hearing or vision
incontinence
what features are important in LD examination and history taking?
- history: pregnancy history, FHx, ADL, developmental, PMH
- MSE
- CVS, resp, neuro
- weight, height, head circumference
- developmental assessment
- hearing and vision
what investigations would be carried on in LD?
- before birth - amniocentesis, chorionic villus sampling, genetic testing and karyotyping
- DS - serum screening, nuchal translucency
- after birth
- bloods - FBC, TFT, glucose, serology infections
- brain imaging - CT head and MRI
