Cotard’s delusion - A type of delusion where the person thinks that they are dead, even when they are alive and healthy.

As an example, adults diagnosed with ADHD rely on ADHD coaches to provide the necessary cues at the appropriate times for the individual. This helps the individual make decisions to prioritize and order tasks. Patients with focal unilateral frontal lobe lesions were observed in different environments such as a doctor's office, a lecture room, a car, a garden, while visiting an apartment where various activities were possible, and in a gift shop. Individuals with this syndrome exhibit striking behavior, it was as if implicit in the environment was an order to respond to the situation in which they found themselves.

Recovered memory syndrome - the suppression of a significant, and usually traumatic memory. There is still debate about whether this is actually a legitimate disorder.

Reward deficiency syndrome (RDS) - People who have this defective gene lack a sufficient number of dopamine receptors in their brains to produce the "neurochemical reward cascade" of the brain. Exposure to prolonged periods of stress and alcohol or other substances can also lead to a corruption of the "cascade function." Those suffering from RDS are unable to produce a feeling of well-being and consequently often self-medicate with substances that help raise the levels of "feel good" chemicals in their system.
