Autism Spectrum Disorder in Hyderabad: Early Diagnosis Matters Most, Evidence-Based Intervention Changes Outcomes

These are two of the most important early autism red flags. Not responding to name and absent pointing by 12–18 months are among the earliest and most reliable signs of ASD. They do not prove autism — a hearing problem can also cause failure to respond to name — but they require urgent investigation. At KIMS, we arrange a hearing test, a developmental assessment, and an early autism evaluation simultaneously when a child under 24 months presents with these concerns. The ADOS-2 can be administered from 12 months with the appropriate module. If autism is identified, ESDM intervention starts immediately — waiting for certainty wastes the most important months of brain plasticity. Please call KIMS on 040-44885000 today. Do not wait to see if he grows out of it.

What you are describing — regression in language and social skills after a period of apparently typical development — is a recognised and important presentation pattern in ASD, sometimes called regressive autism. It occurs in approximately 20–30% of children with ASD. The regression does not mean a progressive neurological disease — it is part of the ASD presentation. However, regression also requires an EEG to exclude Landau-Kleffner syndrome (a rare epileptic disorder causing language regression) and Rett syndrome in girls. At KIMS, regression is taken extremely seriously: EEG, MRI, metabolic screen, genetic testing, and ADOS-2 assessment are all arranged promptly. Regardless of the cause, intervention begins as soon as possible. Please call 040-44885000 urgently.

Yes — and this is one of the most underperformed investigations in Indian ASD management. Chromosomal microarray (also called array CGH or SNP array) detects copy number variants — small deletions and duplications of chromosomal material — that are found as the genetic cause of ASD in approximately 10–15% of patients. Knowing the genetic cause: (1) explains why this happened; (2) identifies whether other family members may be affected or carry the same variant; (3) guides recurrence risk counselling for future pregnancies; (4) identifies specific syndromes (e.g., 16p11.2 deletion, 15q11-13 duplication, 22q11.2 deletion) that have specific medical surveillance requirements. Single-gene causes (Fragile X, Tuberous Sclerosis, Angelman, Phelan-McDermid) have specific treatments or surveillance protocols that change management. At KIMS, chromosomal microarray is the standard first-tier test for every ASD diagnosis. Please call 040-44885000.

The Right of Persons with Disabilities (RPWD) Act, 2016 in India recognises autism spectrum disorder as a specified disability. Under this Act, every child with a disability has the right to inclusive education in any government school, and private schools receiving government aid are also obligated to accommodate children with disabilities. The Act mandates reasonable accommodation — including additional support, assistive devices, and modifications to teaching methods. To exercise these rights, a valid disability certificate from a government hospital or recognised institution is required. At KIMS, we provide a formal diagnostic report and, where needed, assist families in obtaining the disability certificate. KIMS also provides a specific school accommodation letter detailing the child's profile and the specific adjustments required. Please call 040-44885000.

Yes — epilepsy is the most common medical co-morbidity of ASD, occurring in approximately 25–30% of all individuals with ASD and in approximately 40–50% of those with ASD plus intellectual disability. The risk of epilepsy in ASD is highest in early childhood (under 5) and again in adolescence. Seizures in autism may take many forms: absence seizures (brief staring episodes, easily confused with the inattentive behaviour of ASD itself), focal seizures, and tonic-clonic seizures. Any new seizure in a child with ASD requires urgent EEG and neurological assessment at KIMS. Subclinical seizures (seizure activity on EEG without obvious clinical events) are also common in ASD and can worsen behaviour and cognition. At KIMS, the antiseizure medication is selected carefully to avoid agents that may worsen the behavioural or cognitive features of ASD. Please call 040-44885000 urgently for seizure assessment.

Having one child with ASD significantly increases the recurrence risk for subsequent children. The sibling recurrence risk of ASD is approximately 10–20% for a younger sibling (compared to 1–2% population risk). If two children in the family already have ASD, the recurrence risk for a third child is higher still (approximately 25–35%). The recurrence risk depends on the underlying cause: if the first child's ASD has a specific genetic cause identified on chromosomal microarray or gene testing, the recurrence risk can be more precisely calculated based on that specific genetic variant and its inheritance pattern. At KIMS, we provide pre-pregnancy genetic counselling for families with an existing child with ASD. For families where a specific genetic cause has been identified, prenatal testing (CVS or amniocentesis) and pre-implantation genetic diagnosis (PGD) via IVF are options. Please call 040-44885000 for a genetic counselling appointment.
