Psychological Terms — Anabolic Androgenic Steroid (AAS)

Anabolic androgenic steroids (AAS) are synthetic derivatives of testosterone designed to enhance anabolic (tissue-building) effects while also retaining androgenic (masculinizing) properties. AAS increase protein synthesis and promote muscle growth, which has led to widespread non-medical use among bodybuilders, athletes, and individuals seeking enhanced physical appearance or performance. Clinically, these compounds have valid uses in treating delayed puberty, muscle wasting due to chronic illness, and certain forms of anemia.

Psychologically, AAS use is associated with significant mood disturbances. Some individuals report heightened confidence, euphoria, and increased motivation during cycles of use; however, prolonged intake can lead to irritability, aggressiveness (“roid rage”), mood swings, paranoia, and hallucinations. Dependence may develop, resulting in withdrawal symptoms such as fatigue, depressed mood, and reduced libido. Social, legal, and physiological consequences are common, including cardiovascular issues, infertility, and liver pathology.
In psychiatric classification systems, anabolic androgenic steroids fall under substance-related and addictive disorders, particularly when used outside medical indication or taken in dangerous doses.

Psychological Term — Anafranil
Anafranil is a brand name for clomipramine, a tricyclic antidepressant. It is widely prescribed for obsessive–compulsive disorder (OCD), depression, and certain anxiety-related conditions. Clomipramine works by blocking the reuptake of serotonin and norepinephrine, increasing their availability in the brain.
Although effective, it may cause side effects such as drowsiness, dry mouth, dizziness, and sexual dysfunction. Due to its potency in treating OCD, it remains clinically significant despite newer medications with fewer side effects.

Psychological Terms — Anaesthetic 
An anaesthetic is any drug or agent that produces anaesthesia—meaning it reduces or eliminates sensation. Anaesthetics are used to prevent pain and awareness during medical procedures. They may induce complete unconsciousness (general anaesthetic) or numbness in a specific part of the body (local anaesthetic).
General anaesthetics affect the brain globally, preventing sensation and consciousness, while local anaesthetics block nerve transmission near the site of administration. The psychological relevance of anaesthetics includes their effects on consciousness, memory, and pain perception. Some individuals may respond differently based on tolerance, anxiety, or underlying psychological conditions.
The term also functions as an adjective describing anything that causes loss of feeling.

Psychological Terms- Anesthesia 
Anaesthesia refers to a condition in which sensations—including touch and pain—are reduced or eliminated. It can occur naturally due to neurological disorder or be medically induced using drugs or hypnosis.
General anaesthesia affects the entire body and involves unconsciousness, while local anaesthesia blocks sensation only in a specific region. In medical and psychological contexts, forms of anaesthesia may be associated with sensory conversion symptoms or dissociation. Numerous specialized terms exist, such as glove anaesthesia or stocking anaesthesia, referring to sensory loss patterns that correspond more to psychological boundaries than anatomical structures.
The term, coined in 1846 by Oliver Wendell Holmes, derives from Greek roots meaning “without sensation.” Anaesthesia is commonly contrasted with analgesia, which refers more specifically to loss of pain perception.

Psychological Terms – Amniocentesis

Amniocentesis is a prenatal diagnostic procedure in which a physician removes a small sample of amniotic fluid from the uterus using a hollow needle. The fluid is then examined for chromosomal or genetic abnormalities, including Down syndrome.
While primarily medical, its findings have important psychological implications for parental decision-making and counseling.

Psychological Terms – Amnestic Disorder
An amnestic disorder is a clinically recognized mental disorder marked by serious difficulty learning new information and, often, recalling previously learned facts or experiences. This impairment disrupts normal social and occupational functioning.
The condition is not due exclusively to delirium or dementia and may be associated with head trauma, medical illness, drug effects, or toxin exposure. A well-known variant is substance-induced persisting amnestic disorder, commonly linked to prolonged alcohol abuse and resulting vitamin deficiency (especially thiamine).
Etymologically, the term stems from Greek roots meaning “not remembering.”

Psychological Term — Amusia

Amusia is an impairment marked by an inability to recognize, reproduce, or appreciate musical tones or melodies despite normal hearing and cognitive functioning. The condition may be congenital — present from birth — or acquired due to brain injury, particularly in the right temporal lobe. Congenital amusia affects approximately 4–5% of the general population and is believed to reflect a genetic variation that disrupts the brain’s encoding and processing of pitch structure. Individuals may struggle to detect differences in musical notes, recognize familiar tunes, or sing in tune.

Amusia can extend beyond melody perception to include rhythm and timing deficits, though pitch discrimination is most consistently affected. The condition has been closely studied to understand how the brain processes auditory stimuli. Research suggests that abnormalities in neural pathways connecting auditory cortex with frontal regions may limit conscious access to pitch patterns. Notably, some well-known historical figures — including Che Guevara and economist Milton Friedman — are believed to have had amusia.
​
Amusia differs from conditions such as dysmelodia or dysmusica, which may represent partial impairments. The disorder emphasizes that musical ability is not solely dependent on cultural exposure but reflects specialized neural circuitry.

Psychological Terms — AmurakhAmurakh refers to a culturally specific behavior pattern related to the condition known as latah, found primarily in Southeast Asia. Latah is characterized by exaggerated startle responses, involuntary mimicry, and compulsive obedience to commands. Individuals with latah may imitate words or gestures, engage in automatic speech, or perform socially inappropriate acts when startled. These behaviors appear reflexive rather than deliberate, suggesting underlying altered states of consciousness.
Amurakh is considered one culturally recognized variant within this broader syndrome. Although precise manifestations may vary, individuals may display heightened suggestibility, repeating or complying with commands regardless of content. Episodes are often brief, typically triggered by sudden surprise or stress. Cultural beliefs sometimes interpret latah-related states as spirit influence, ritual imbalance, or social performance, depending on the local explanatory framework.
Modern interpretations view amurakh and related forms of latah as examples of culture-bound syndromes — patterns of behavior that appear within specific cultural contexts and may not directly map onto Western psychiatric categories. The condition highlights the role of cultural norms and expectations in shaping symptom expression and meaning.
