Hi Mckenziebelle,

This is a great question! First, for those not familiar with the acronym- SPD is short for sensory processing disorder.

My understanding of SPD is that it is often seen with and without ADHD and is often misdiagnosed as ADHD and vice versa. But it gets a bit complicated because most people with ADHD do have sensory issues, and many with SPD have attentional problems.

The treatment used for people with ADHD typically are the stimulants, whereas those with SPD are usually treated with occupational therapy, which often includes a "sensory diet" to help with sensory issues.

I am becoming more and more interested in sensory issues and will be curious to see how this plays out, ie have some or many people with ADHD been misdiagnosed and instead, have SPD?

There's an interesting book that I would recommend on this topic; it's titled "Too Loud, Too Bright, Too Fast, Too Tight," by Sharon Heller. It's geared towards adults with sensory issues.

The book "The Out-of-Synch Child" by Carol S. Kranowitz, covers sensory issues in children.

Thanks for posting this interesting question!
