Can MRI or a genetic analysis detect ASD syndrome?

Question

Hello doctor,

Is it possible to diagnose ASD syndrome (autism spectrum disorder) through an MRI, a set of DaT Scan images, genetic test analysis, or other procedures?

Kindly help.

Thank you.

Answer 1

Hello,

Welcome to icliniq.com.

I understand your concern and explain that there is no specific test to diagnose ADHD (attention deficit hyperactivity disorder). Anyway, a genetic test can be tried because a mutation in the TPH2 (Tryptophan hydroxylase 2) gene on chromosome 12q21 is associated with susceptibility to ADHD.

Brain imaging, such as functional MRI (magnetic resonance imaging) or SPECT (single-photon emission computed tomography) scan, has been helpful in ADHD.

ADHD is a clinical diagnosis where the patient has to fulfill some clinical criteria.

I hope you will find this information helpful.

Kind regards.

Answer 2

Hello,

Welcome back to icliniq.com.

Regarding your concern, let me explain as follows:

1) The beta waves usually show increased alertness or a lot of stress and thinking. In ADHD or Asperger syndrome, beta and alpha waves are decreased, while there is an increase in delta waves activity, mainly in the frontal lobes.

2) The clinical examination may be normal (in most of the patients). Sometimes brisk or increased reflexes may be present, especially when the patient has cerebral palsy.

I hope you will find this answer helpful.

Kind regards.
