Thought Disorder
A thought disorder (TD) is a disturbance in cognition which affects language, thought and communication. Psychiatric and psychological glossaries in 2015 and 2017 identified thought disorders as encompassing poverty of ideas, paralogia (a reasoning disorder characterized by expression of illogical or delusional thoughts), word salad, and delusions—all disturbances of thought content and form. Two specific terms have been suggested—content thought disorder (CTD) and formal thought disorder (FTD). CTD has been defined as a thought disturbance characterized by multiple fragmented delusions, and the term ''thought disorder'' is often used to refer to an FTD: a disruption of the form (or structure) of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses (including mood disorders, dementia, mania, and neurological diseases). Disorganized speech leads to an inference of disorgani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental disorder, mental conditions. These include matters related to cognition, perceptions, Mood (psychology), mood, emotion, and behavior. Initial psychiatric assessment of a person begins with creating a Medical history, case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological tests may be conducted. On occasion, neuroimaging or neurophysiological studies are performed. Mental disorders are diagnosed in accordance with diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited by the World Health Organization (WHO), and the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013. Treatment may include psychotropics (psychiatric medicines), psychotherapy, su ...

Tangentiality
Tangential speech or tangentiality is a communication disorder in which the train of thought of the speaker wanders and shows a lack of focus, never returning to the initial topic of the conversation.''Forensic Aspects of Communication Sciences and Disorders'' by Dennis C. Tanner 2003 page 289 It commonly occurs in situations where an individual experiences high anxiety, as a manifestation of acute psychosis, dementia, or states of delirium. It is less severe than logorrhea and may be associated with the middle stage in dementia. It is, however, more severe than circumstantial speech, in which the speaker wanders but eventually returns to the topic. Some adults with right hemisphere brain damage exhibit tangential speech. Those who exhibit tangential speech may also have related symptoms, such as seemingly inappropriate, self-centered social responses and deteriorations in conversation capabilities (including maintaining appropriate eye contact and staying on topic).''Perspectiv ...

Major Depressive Disorder
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive depression (mood), low mood, low self-esteem, and anhedonia, loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this syndrome, symptom cluster under mood disorders in the 1980 version of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after low back pain, lower back pain. The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by family or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time o ...

Phobia
A phobia is an anxiety disorder, defined by an irrational, unrealistic, persistent and excessive fear of an object or situation. Phobias typically result in a rapid onset of fear and are usually present for more than six months. Those affected go to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the object or situation cannot be avoided, they experience significant Distress (medicine), distress. Other symptoms can include fainting, which may occur in Blood phobia, blood or injury phobia, and panic attacks, often found in agoraphobia and emetophobia. Around 75% of those with phobias have multiple phobias. Phobias can be divided into specific phobias, social anxiety disorder, and agoraphobia. Specific phobias are further divided to include certain animals, natural environment, blood or injury, and particular situations. The most common are fear of spiders, fear of snakes, and fear of heights. Specific phobias may be caused by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magical Thinking
Magical thinking, or superstitious thinking, is the belief that unrelated events are causally connected despite the absence of any plausible causal link between them, particularly as a result of supernatural effects. Examples include the idea that personal thoughts can influence the external world without acting on them, or that objects must be causally connected if they resemble each other or have come into contact with each other in the past. Magical thinking is a type of fallacious thinking and is a common source of invalid causal inferences. Unlike the confusion of correlation with causation, magical thinking does not require the events to be correlated. The precise definition of magical thinking may vary subtly when used by different theorists or among different fields of study. In psychology, magical thinking is the belief that one's thoughts by themselves can bring about effects in the world or that thinking something corresponds with doing it. These beliefs can cause a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compulsive Behavior
Compulsive behavior (or compulsion) is defined as performing an action persistently and repetitively. Compulsive behaviors could be an attempt to make obsessions go away. Compulsive behaviors are a need to reduce apprehension caused by internal feelings a person wants to abstain from or control. A major cause of compulsive behavior is obsessive–compulsive disorder (OCD).(1996). Obsessive Compulsive Disorder: Decade of the Brain. National Institutes of Health. "Compulsive behavior is when someone keeps doing the same action because they feel like they have to, even though they know these actions do not align with their goals." There are many different types of compulsive behaviors including Compulsive buying disorder, shopping, hoarding, Compulsive overeating, eating, Problem gambling, gambling, trichotillomania and Dermatillomania, picking skin, itching, Obsessive–compulsive disorder, checking, Arithmomania, counting, washing, Hypersexuality, sex, and more. Also, there are cul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intrusive Thought
An intrusive thought is an unwelcome, involuntary thought, image, or unpleasant idea that may become an obsession, is upsetting or distressing, and can feel difficult to manage or eliminate. When such thoughts are paired with obsessive–compulsive disorder (OCD), Tourette syndrome (TS), depression, autism, body dysmorphic disorder (BDD), and sometimes attention deficit hyperactivity disorder (ADHD), the thoughts may become paralyzing, anxiety-provoking, or persistent. Intrusive thoughts may also be associated with episodic memory, unwanted worries or memories from OCD,Baer (2001), pp. 58–60 post-traumatic stress disorder (PTSD), other anxiety disorders, eating disorders, or psychosis. Intrusive thoughts, urges, and images are of inappropriate things at inappropriate times, and generally have aggressive, sexual, or blasphemous themes.Baer (2001), p. xiv. Description General Many people experience the type of negative and uncomfortable thoughts that people with more intrusive t ...

Delusion
A delusion is a fixed belief that is not amenable to change in light of conflicting evidence. As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs ''are'' able to change or readjust their beliefs upon reviewing the evidence. However: "The distinction between a delusion and a strongly held idea is sometimes difficult to make and depends in part on the degree of conviction with which the belief is held despite clear or reasonable contradictory evidence regarding its veracity." Delusions have been found to occur in the context of many pathological states (both general physical and mental) and are of particular diagnostic importance in psychosis, psychotic disorders including schizophrenia, paraphrenia, Mania, manic episodes of bipolar disorder, and psychotic depression. Types Delusions are categorized into four differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delirium
Delirium (formerly acute confusional state, an ambiguous term that is now discouraged) is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days. As a syndrome, delirium presents with disturbances in attention, awareness, and higher-order cognition. People with delirium may experience other neuropsychiatric disturbances including changes in psychomotor activity (e.g., hyperactive, hypoactive, or mixed level of activity), disrupted sleep-wake cycle, emotional disturbances, disturbances of consciousness, or altered state of consciousness, as well as perceptual disturbances (e.g., hallucinations and delusions), although these features are not required for diagnosis. Diagnostically, delirium encompasses both the syndrome of acute confusion and its underlying organic process known as an acute encephalopathy. ...

Tourette Syndrome
Tourette syndrome (TS), or simply Tourette's, is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements. These are typically preceded by an unwanted urge or sensation in the affected muscles known as a premonitory urge, can sometimes be suppressed temporarily, and characteristically change in location, strength, and frequency. Tourette's is at the more severe end of a spectrum disorder, spectrum of tic disorders. The tics often go unnoticed by casual observers. Tourette's was once regarded as a rare and bizarre syndrome and has popularly been associated with coprolalia (the utterance of obscene words or socially inappropriate and derogatory remarks). It is no longer considered rare; about 1% of school-age children and adolescents are Tourette syndrome#Epidemiology, estimated to hav ...

Echolalia
Echolalia is the unsolicited repetition of vocalizations made by another person; when repeated by the same person, it is called palilalia. In its profound form it is automatic and effortless. It is one of the echophenomena, closely related to echopraxia, the automatic repetition of movements made by another person; both are "subsets of imitative behavior" whereby sounds or actions are imitated "without explicit awareness". Echolalia may be an immediate reaction to a stimulus or may be delayed. Echolalia occurs in many cases of autism spectrum disorder and Tourette syndrome. It may also occur in several other neurological conditions such as some forms of dementia or stroke-related aphasia. The word "echolalia" is derived from the Greek (''ēchō''), meaning "echo" or "to repeat", and (''laliá'') meaning "speech" or "talk" (of onomatopoeic origin, from the verb (''laléo''), meaning "to talk"). Signs and symptoms Echolalia can be categorized as either immediate (occurrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clanging
Clanging (or clang associations) is a symptom of mental disorders, primarily found in patients with schizophrenia and bipolar disorder. This symptom is also referred to as association chaining, and sometimes, glossomania. Steuber defines it as "repeating chains of words that are associated semantically or phonetically with no relevant context". This may include compulsive rhyming or alliteration without apparent logical connection between words. Clanging refers specifically to behavior that is situationally inappropriate. While a poet rhyming is not evidence of mental illness, disorganized speech that impedes the patient's ability to communicate is a disorder in itself, often seen in schizophrenia. Example This can be seen by a section of a 1974 transcript of a patient with schizophrenia: The speaker makes semantic chain associations on the topic of cats, to the colour of her cat, which (either the topic of colours/patterns, or the topic of pets) leads her to jump from her goldf ...
