Attention-deficit/ hyperactivity disorder

What is ADHD?

ADHD is a neurological disorder that causes hyperactivity, impulsiveness, and attention difficultly.

What Body System does this affect?

The Brain

Scientists think that ADHD could be caused by lower levels of dopamine in regions of the brain for concentration. When a normal brain gets information it picks the important message and leaves the rest out. A brain with ADHD gets information but it floods thoughts and are unable to be filtered out, they may not even be able to respond back to the information they're getting. The frontal lobes are the part of the brain that is under active in the brain for someone with ADHD compared with a person that doesn't.


Diagnosis is made after examination by a Pediatrician, Psychiatrist, or Psychologist. An SPECT is to measure blood flow to certain parts of the brain. A PET measures tiny sugar molecules that have been tagged with radioactive marker that makes them show up on the scan. The sugar collects in the brain that makes the most used areas light up, by weather the the lights are on or off in significant parts of the brain.

Signs and Symptoms

ADHD in children symptoms are divided into two behavioral categories: intention/ hyperactivity.

An intention child has: a hard time concentrating

trouble finishing school assignments

easily distracted


A hyperactive child:


talks excessively

has trouble waiting their turn.

Most of the time ADHD comes with other neurological disorders such as Depression, Bipolar Disorder, Anxiety, and Conduct disorder


For ADHD treatment can be from medication and or behavioral therapies. One of the widely used medications is Methylphenidate, it is a stimulant medication that boosts brain chemicals called neurotransmitters. Other examples include dextroamphetamine (Dexedrine), dextoamphetamine- amphetamine (Adderal XR),and lisdexamphetamine (Vyvanse). While taking behavioral therapies many have shown great results being able to contain themselves more. Although rare heart-related deaths have occurred while on stimulant medications in children and teenagers. If the possibility of increased death is true although still unproved it's believed to be in people with an underlying heart disease/ defect.
What ADHD Feels Like


Often runs in families
