Brief Answer:
Cerebral palsy could be considered possibility
Detailed Answer:
Greetings
Dear Madam,
Many of the developmental delay could be due to idiopathic cause(There is no definite cause).
Possibility of Cerebral Palsy can also be considered.
I hope he has also been thoroughly evaluated for
Toxoplasmosis and ruled out by appropriate investigation.
In our setting we have dedicated Child developmental Clinic(CDC), which regularly assess the developmental milestone and help in
Physiotherapy and
Rehabilitation.
As he seems to have failure to thrive i would also suggest you the following which are the commonest cause for failure to thrive and stunted growth(as his growth is in 3rd percentile only)( Management is Multi-speciality and multi-modality)
1. Rule out
Urinary Tract infection: Sub-clinical urinary infection may present with developmental delay, stunted growth and
Renal Osteodystrophy and affection of dentition. Urine examination and Ultrasound abdomen will suffice
2. Presence of Occult Spinal Dyraphism: Thorough neurological examination especially of the back to rule out any spine defect with herniation of nerves(
Meningocele and Meningo-Myelocele)
3. Toxoplasmosis:
4. Reassessment for possibility of Gastro-oesophageal reflux(GERD): Acid reflux in mouth may cause early dental carries.
GERD should especially be considered in a diagnosis of child presenting with rapid carries of tooth.
I would suggest you to discuss these probabilities with your
Pediatrician and i am sure things an be definitely be taken care of.
I do understand the difficulties and frustration you would have gone through.
Do get a reassessment , things can be taken cre off.
Do write directly to me if you need any suggestion anytime.
Assuring you the best always
Take Care
Best Regards
