Hello,
I recommend he be evaluated by his
pediatrician for the following metabolic profiles if not already done:
THYROID FUNCTION (using FT4 and TSH), LIVER ENZYMES and INR to establish liver integrity, COPPER LEVELS in 24 hr. urine.
His pediatrician could also order an MRI of the brain (without contrast to start) which can be repeated WITH contrast if something suspicious surfaces on the first one.
If any of the metabolic profiles come back POSITIVE for something out of balance then, it should be corrected (with a consultation to appropriate specialist if necessary).
If the profiles are NEGATIVE for metabolic abnormalities and the imaging studies are negative for architectural problems then, a referral to a PEDIATRIC
NEUROLOGIST would be in order.
The most COMMON pediatric
movement disorder consistent with your description is
ESSENTIAL TREMOR which is usually successfully controlled with medication.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
