Personality Change Due To Another Medical Condition
Organic personality disorder (OPD) or secondary personality change, is a condition described in the ICD-10 and ICD-11 respectively. It is characterized by a significant personality change featuring abnormal behavior due to an underlying traumatic brain injury or another pathophysiological medical condition affecting the brain. Abnormal behavior can include but is not limited to apathy, paranoia and disinhibition. The DSM-5-TR, which is the latest edition of the DSM , lists personality change due to another medical condition with the ICD-10-CM code F07.0, which corresponds to what the ICD-10 denotes as OPD. In the ICD-10, it is described as a mental disorder and not included in the classification group of personality disorders. In the ICD-11, it is described as a syndrome. Signs and symptoms OPD is associated with a large variety of symptoms, such as deficits in cognitive function, dysfunctional/abnormal behaviour, psychosis, neurosis, higher irritability and altered emotion ...

ICD-10
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, was endorsed by the Forty-third World Health Assembly in 1990, and came into effect in member states on January 1, 1993. ICD-10 was replaced by ICD-11 on January 1, 2022. While WHO manages and publishes the base version of the ICD, several member states have modified it to better suit their needs. In the base classification, the code set allows for more than 14,000 different codes and permits the tracking of many new diagnoses compared to the preceding ICD-9. Through the use of optional sub-classifications, ICD-10 allows for specificity regarding the cause, manifestation, location, severity, and type of injury or disease. The adapted versions may differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Function
Cognitive skills are skills of the mind, as opposed to other types of skills such as motor skills, social skills or life skills. Some examples of cognitive skills are literacy, self-reflection, logical reasoning, abstract thinking, critical thinking, introspection and mental arithmetic. Cognitive skills vary in processing complexity, and can range from more fundamental processes such as perception and various memory functions, to more sophisticated processes such as decision making, problem solving and metacognition. Specialisation of functions Cognitive science has provided theories of how the brain works, and these have been of great interest to researchers who work in the empirical fields of brain science. A fundamental question is whether cognitive functions, for example visual processing and language, are autonomous modules, or to what extent the functions depend on each other. Research evidence points towards a middle position, and it is now generally accepted that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsolateral Prefrontal Cortex
The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. The DLPFC is not an anatomical structure, but rather a functional one. It lies in the middle frontal gyrus of humans (i.e., lateral part of Brodmann's area (BA) 9 and 46). In macaque monkeys, it is around the principal sulcus (i.e., in Brodmann's area 46). Other sources consider that DLPFC is attributed anatomically to BA 9 and 46 and BA 8, 9 and 10. The DLPFC has connections with the orbitofrontal cortex, as well as the thalamus, parts of the basal ganglia (specifically, the dorsal caudate nucleus), the hippocampus, and primary and secondary association areas of neocortex (including posterior temporal, parietal, and occipital areas). The DLPFC is also the end point for the dorsal pathway (stream), which is concerned with how t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterior Cingulate Cortex
In human brains, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33. It is involved in certain higher-level functions, such as attention allocation, reward anticipation, decision-making, impulse control (e.g. performance monitoring and error detection), and emotion. Some research calls it the anterior midcingulate cortex (aMCC). Anatomy The anterior cingulate cortex can be divided anatomically based on cognitive (dorsal), and emotional ( ventral) components. The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex, as well as the motor system and the frontal eye fields, making it a central station for processing top-down and bottom-up stimuli and assigning appropriate control to other areas in the brain. By contrast, the ventral part of the ACC is connected with the amygdala, nucleu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbitofrontal Cortex
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47. The OFC is functionally related to the ventromedial prefrontal cortex.Phillips, LH., MacPherson, SE. & Della Sala, S. (2002). 'Age, cognition and emotion: the role of anatomical segregation in the frontal lobes: the role of anatomical segregation in the frontal lobes'. in J Grafman (ed.), Handbook of Neuropsychology: the frontal lobes. Elsevier Science, Amsterdam, pp. 73-98. Therefore, the region is distinguished due to the distinct neural connections and the distinct functions it performs.Barbas H, Ghashghaei H, Rempel-Clower N, Xiao D (2002) Anatomic basis of functional specialization in prefrontal cortices in primates.

Oppositional Defiant Disorder
Oppositional defiant disorder (ODD) is listed in the DSM-5 under ''Disruptive, impulse-control, and conduct disorders'' and defined as "a pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness." This behavior is usually targeted toward peers, parents, teachers, and other authority figures, including law enforcement officials. Unlike Conduct Disorder (CD), those with ODD do not generally show patterns of aggression towards random people, violence against animals, destruction of property, theft, or deceit. One-half of children with ODD also fulfill the diagnostic criteria for ADHD.Golubchik, Pavel, Shalev, Lilach, Tsamir, Dina, Manor, Iris, Weizman, Abraham. "High pretreatment cognitive impulsivity predicts response of oppositional symptoms to methylphenidate in patients with attention-deficit hyperactivity disorder/oppositional defiant disorder".

Attention Deficit Hyperactivity Disorder
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and Developmental psychology, developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, Cognitive inhibition, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished Quality of life (healthcare), quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of su ...

Frontal Lobe
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a Sulcus (neuroanatomy), groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral sulcus (Sylvian fissure). The most anterior rounded part of the frontal lobe (though not well-defined) is known as the frontal pole, one of the three Cerebral hemisphere#Poles, poles of the cerebrum. The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex. The nonprimary motor cortex is a functionally defined portion of the frontal lobe. There are four principal Gyrus, gyri in the frontal lobe. The precentral gyrus is directly anterior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language Processing In The Brain
In psycholinguistics, language processing refers to the way humans use words to communicate ideas and feelings, and how such communications are processed and understood. Language processing is considered to be a uniquely human ability that is not produced with the same grammatical understanding or systematicity in even human's closest primate relatives. Throughout the 20th century the dominant model for language processing in the brain was the Geschwind–Lichteim–Wernicke model, which is based primarily on the analysis of brain-damaged patients. However, due to improvements in intra-cortical electrophysiological recordings of monkey and human brains, as well non-invasive techniques such as fMRI, PET, MEG and EEG, an auditory pathway consisting of two parts has been revealed and a two-streams model has been developed. In accordance with this model, there are two pathways that connect the auditory cortex to the frontal lobe, each pathway accounting for different lin ...

Emotional Lability
In medicine and psychology, emotional lability is a Medical sign, sign or symptom typified by exaggerated changes in mood or affect (psychology), affect in quick succession. Sometimes the emotions expressed outwardly are very different from how the person feels on the inside. These strong emotions can be a disproportionate response to something that happened, but other times there might be no trigger at all. The person experiencing emotional lability usually feels like they do not have control over their emotions. For example, someone might cry uncontrollably in response to any strong emotion even if they do not feel sad or unhappy. Emotional lability is seen or reported in various conditions including borderline personality disorder, histrionic personality disorder, post-traumatic stress disorder, hypomanic or manic episodes of bipolar disorder, and neurological disorders or brain injury (where it is termed pseudobulbar affect), such as after a stroke. It has sometimes been found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotional Expression
An emotional expression is a behavior that communicates an emotional state or attitude. It can be verbal or nonverbal, and can occur with or without self-awareness. Emotional expressions include facial movements like smiling or scowling, simple behaviors like crying, laughing, or saying " thank you," and more complex behaviors like writing a letter or giving a gift. Individuals have some conscious control of their emotional expressions;Dorset Research & Development Support Unit, 2003"Emotional Expression." Retrieved on: July 23, 2007. however, they need not have conscious awareness of their emotional or affective state in order to express emotion. Researchers in psychology have proposed many different and often competing theoretical models to explain emotions and emotional expression, going as far back as Charles Darwin's discussion of emotion as an evolved capacity. Though there is no universally accepted theory of emotion, theorists in emotion agree that experience of emot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irritability
Irritability is the excitatory ability that living organisms have to respond to changes in their environment. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli. When reflecting human emotion and behavior, it is commonly defined as the tendency to react to stimuli with negative affective states (especially anger) and temper outbursts, which can be aggressive. Distressing or impairing irritability is important from a mental health perspective as a common symptom of concern and predictor of clinical outcomes. Definition Irritability is the excitatory ability that living organisms have to respond to changes in their environment. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli. Irritability can be demonstrated in behavioral responses to both physiological and behavioral stimuli, including environmental, situ ...
