Alzheimer's disease accounts for somewhere between 60 to 80% of all dementia cases. "Alzheimer's" and "dementia" are sometimes used interchangeably, but this is an error due to the great overlapping in cases. All Alzheimer's patients have dementia, but not all dementia patients have Alzheimer's disease.

Negative symptoms are thoughts, feelings, or behaviors that are present in the average person but diminished in a person with a mental disorder. Diminished appetite is the only option that is not a negative symptom of schizophrenia.

"Insanity" is not a medical term used to diagnose a patient, it is purely a legal term. It serves a very important purpose in legal affairs, since it is used to differentiate between what a person can be held responsible for. A person who is legally adjudicated as "insane" is, in the opinion of the court, unable to understand the consequences of their actions and, usually, unable to effectively assist their counsel in their legal defense.

Alogia can be one of the symptoms that paranoid schizophrenic experiences. It is a negative symptom characterized by a lack of language production as a result of "blocked thought." This is often manifested in short, empty phrases.

Current classification systems are categorical in nature, meaning that there are distinct categories for each mental illness that does not necessarily overlap with other diagnoses. A dimensional system that takes into account the overlapping nature of mental illness along a spectrum of severity has been proposed, but it has limited utility.

The psychodynamic approach in psychology holds that internal drives for pleasure (the id) is in constant conflict with the rational mind (the ego) and the moral mind (the superego). When these forces are unbalanced, they can manifest themselves as a variety of mental disorders.

Developmental psychopathology is the study of the development of psychological disorders, including autism, ADHD, and schizophrenia. This subfield of psychopathology focuses on a life course perspective in examining the trajectory of psychological disorders.

Post-traumatic stress disorder develops after a person is exposed to one or more traumatic events, including war, injury, assault, and natural disasters. PTSD is characterized by recurring flashbacks of the traumatic event, nightmares, hyperarousal, and high levels of anxiety.

Although many children and adolescents may suffer from generalized anxiety disorder (GAD), it is generally not diagnosed until later in development. The other four choices are more frequently diagnosed in those under 18 years old.

Serotonin is the major neurotransmitter that regulates mood, sleep, and motivation. A lack of serotonin can lead to depression, OCD, and eating disorders. Too much serotonin can decrease motivation. Serotonin levels can be regulated through selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, tricyclic antidepressants, and other drugs.

Cognitive-behavioral therapy (CBT) is a structured, short-term therapeutic technique that aims to change a client's maladaptive cognitions and behaviors into more realistic and/or adaptive ones. CBT is commonly used for those with various mood and anxiety disorders.

Free association is a common tenet of psychoanalysis that allows clients to speak for themselves. Free association allows the therapist to figure out the client's unconscious motives and desires.

Humanistic therapy focuses on boosting patient's self-fulfillment via growth in self-awareness and self-acceptance. Active listening is a technique that may be used in humanistic therapies, such as client-centered therapy, but is a tool used within that kind of therapy, not a discrete kind of therapy unto itself. The other options would be considered behavioral therapy.

Antipsychotic drugs are popular and often effective at treating symptoms of schizophrenia such as delusions or hallucinations but not the behaviors associated with the disorder. Long-term behavioral therapy is often necessary to treat behaviors that come with the mental disorder.

Lithium is the most widely used and studied medications for bipolar disorders. They also have a role in treating depression and mania, acutely and long term. Once ingested, lithium becomes prevalent in the central nervous system (CNS), and can bind to a number of receptors in order to block norepinephrine production. It can also interact with neurotransmitters in order to cause a release of seratonin.

Selective serotonin reuptake inhibitors (SSRIs) are commonly used to treat mood disorders. The other choices are used for other types of mental illnesses.

SSRIs (selective serotonin reuptake inhibitors) are commonly prescribed for depressed patients to increase the amount of serotonin in their bodies. Having a greater amount of serotonin is associated with experiencing more positive emotions.

Lithium is typically used to treat the manic symptomology associated with bipolar disorder.

Selective serotonin reuptake inhibitors interfere with serotonin transport in the brain's synapses and can work to elevate mood. SSRIs are used to treat depression, obsessive-compulsive disorder, schizophrenia, bipolar disorder, and post-traumatic stress disorder. Treatment for personality disorders with SSRIs is not successful.

Benzodiazepines such as Xanax, Klonopin, Ativan, and Valium, act like sedatives, but without their sleep-inducing effect. These medications can be effective in the treatment of panic disorders.

Selective serotonin reuptake inhibitors (SSRIs) such as Zoloft, Paxil, and Luvox, are mood stabilizers and are used to treat depression. Nardil is a monoamine oxidase inhibitor (MAOI) useful in the treatment of post-traumatic stress disorder by reducing nightmares and insomnia. Catapres and Inderal, which are antiadrenergic agents, are also useful in the treatment of post-traumatic stress disorder. Antiadrenergic agents reduce startle reactions. Lithium is a mood stabilizer used to treat bipolar disorder and schizophrenia.
