Summary
Self-injurious behaviour (SIB) shares neurobiological underpinnings with other repetitive behaviors like stereotypy and tics. Understanding these links can lead to new treatments for SIB.
Area of Science:
- Neuroscience
- Genetics
- Developmental Psychology
Background:
- Self-injurious behaviour (SIB) is a significant challenge in neurodevelopmental disorders.
- The neurobiological basis of SIB remains poorly understood, hindering treatment.
- Genetic mutations are linked to increased SIB prevalence.
Purpose of the Study:
- To explore the shared neurobiology between SIB and other repetitive behaviors.
- To leverage knowledge from related disorders to understand SIB.
- To identify potential therapeutic targets for SIB.
Main Methods:
- Review of evidence linking SIB with stereotypy, compulsions, and tics.
- Comparison of phenotypic similarities and co-morbidities.
- Analysis of existing neurobiological data from related disorders and animal models.
Main Results:
- SIB, stereotypy, compulsions, and tics share phenotypic similarities and common triggers.
- Dysfunction in cortical basal ganglia circuitry is implicated in repetitive behaviors.
- Studies on related disorders offer testable hypotheses for SIB pathophysiology.
Conclusions:
- Available data from clinical and animal models can refine hypotheses on SIB.
- Testing these hypotheses may yield effective pharmacological strategies for SIB.
- Understanding shared pathophysiology is key to developing novel SIB treatments.

01:28Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
01:19Introduction to Psychological Disorders
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

01:30Positive Symptoms of Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes loosely...

01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:30Dissociative Identity Disorder
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
