Anorexia nervosa, often referred to simply as anorexia, is an eating disorder characterized by a low weight, fear of gaining weight, a strong desire to be thin, and food restriction. Many people with anorexia see themselves as overweight even though they are in fact underweight. If asked they usually deny they have a problem with low weight. Often they weigh themselves frequently, eat only small amounts, and only eat certain foods. Some will exercise excessively, force themselves to vomit, or use laxatives to produce weight loss.
A phobia is a type of anxiety disorder, defined by a persistent fear of an object or situation. The phobia typically results in a rapid onset of fear and is present for more than six months. The affected person will go to great lengths to avoid the situation or object, typically to a degree greater than the actual danger posed. If the feared object or situation cannot be avoided, the affected person will have significant distress.
15. Parkinson’s Disease
Parkinson’s disease (PD) is a long term disorder of the central nervous system that mainly affects the motor system. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. Thinking and behavioral problems may also occur. Dementia becomes common in the advanced stages of the disease. Depression and anxiety are also common occurring in more than a third of people with PD. Other symptoms include sensory, sleep, and emotional problems.
Addiction is a medical condition characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. The two properties that characterize all addictive stimuli are that they are reinforcing (i.e., they increase the likelihood that a person will seek repeated exposure to them) and intrinsically rewarding (i.e., perceived as being positive or desirable)
17. Narcissistic Personality Disorder
Narcissistic personality disorder (NPD) is a long-term pattern of abnormal behavior characterized by exaggerated feelings of self-importance, an excessive need for admiration, and a lack of understanding of others’ feelings. People affected by it often spend a lot of time thinking about achieving power or success, or about their appearance. They often take advantage of the people around them.
Megalomania is often used loosely to mean having delusional fantasies of wealth, power, or omnipotence.
Paranoia is a thought process believed to be heavily influenced by anxiety or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes persecutory, or beliefs of conspiracy concerning a perceived threat towards oneself (e.g. “Everyone is out to get me”). Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame. Making false accusations and the general distrust of others also frequently accompany paranoia. For example, an incident most people would view as an accident or coincidence, a paranoid person might believe was intentional.
20. Alzheimer’s Disease
Alzheimer’s disease (AD), is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. It is the cause of 60% to 70% of cases of dementia. The most common early symptom is difficulty in remembering recent events (short-term memory loss). As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost),mood swings, loss of motivation, not managing self care, and behavioural issues.
