ADHD Not One Size Fits All: New Study Reveals 3 Biotypes
4 Mar
Summary
- ADHD may have three distinct biotypes with unique brain patterns.
- Study analyzed chemical and structural brain patterns in children.
- Findings could lead to personalized ADHD therapeutic strategies.
New research indicates that Attention Deficit Hyperactivity Disorder (ADHD) might present in three distinct subtypes, challenging the traditional view of the condition. This brain imaging study, published in JAMA Psychiatry, analyzed both chemical and structural brain patterns in hundreds of children diagnosed with ADHD.
The analysis revealed that not all ADHD brain activity is the same, with three unique patterns emerging. These "biotypes" possess distinct clinical-neural profiles. This finding holds significant promise for developing personalized treatment strategies tailored to individual needs, moving beyond current generalized approaches.
Consultant psychiatrist Dr. Shyamal Mashru described emotional dysregulation, a potential aspect of ADHD, as an amplified emotional response. Hyperactivity can manifest as high energy and restlessness, while impulsivity involves acting without thought. Inattentiveness may stem from a lack of attention regulation, with focus dispersed across multiple stimuli rather than a deficit of attention itself.
