A misunderstood medical condition where one has a chronic deficiency in a neurotransmitter called dopamine which is a brain chemical which helps one to become more motivated and complete tasks easier, hence why individuals suffering from ADHD may take longer to do certain tasks such as school work, but that does not mean that they can't get it done. People with ADHD may present signs of low confidence which is also to do with deficiency of dopamine as dopamine provides the feeling of reward after completing a difficult task. Unfortunately there is currently no cure for ADHD, however there are different methods of treating the conditions such as CBT (cognitive behavioural therapy), but it's probably better to take stimulant meds to increase the quantities of dopamine in the brain. Research shows that stimulant meds are effective in 70%-80% of patients with moderate or severe ADHD.
If you or a your child presents signs of ADHD, consult GP so they can refer the patient to a psychiatrist if they are certain one is showing signs of the condition.
