Bipolar disorder is marked by extreme shifts in mood that can vary between deep depression and mania, an abnormally elevated mood.
Borderline personality disorder
Like bipolar disorder, borderline personality disorder is marked by a lack of emotional regulation. People with the disorder have unpredictable mood swings and self-image problems that lead to relationship difficulties.
Unlike fleeting moments of stress, anxiety disorders are chronic fears or worries that significantly impact your ability to function.
- Panic disorder, or repeated episodes of sudden fear and dread
- Obsessive-compulsive disorder, or frequent, repeated thoughts leading to repetitive behavior (such as excessive hand-washing)
- Generalized anxiety disorder, or an excessive worry that lasts for months and often has physical symptoms such as headache or fatigue
Schizophrenia is a severe brain disorder that can cause psychotic reactions, including hallucinations (seeing things or hearing voices that arent there), delusions (thoughts not based in reality), paranoia (the belief that something or someone is out to “get” you), disorganized speech and thoughts, a lack of motivation, social withdrawal, and flat or blunted emotions that can mimic depression.
ADHD can affect both children and adults. Its marked by impulsivity, inattention, and hyperactivity. However, distinguishing between ADHD and bipolar disorder is more difficult in young patients.
Some drugs, such as cocaine and amphetamines , can mimic mania, while alcohol abuse can mimic (and even cause) depression.
