Identifying latent schizophrenia early offers a window of...
Latent Inhibition Disorder: Understanding Symptoms, Causes, and Effective Therapies
Latent inhibition disorder is a cognitive phenomenon in which the brain’s natural ability to filter out familiar, nonessential stimuli becomes impaired. When this filtering mechanism weakens, individuals may feel inundated with background sounds, sights, or sensations that most people effortlessly ignore. As a result, everyday environments can feel overwhelming, leading to distractibility, anxiety, or creative breakthroughs, depending on how...
Latah: Diagnosis, Behavioral Signs, and Neuropsychiatric Management
Latah is a culturally bound syndrome marked by exaggerated startle reflexes and automatic obedience, primarily reported among older adults in Malaysia and Indonesia. Characterized by involuntary mimicry (echolalia, echopraxia), compulsive obedience, and trance-like behaviors following a sudden shock, Latah disrupts social functioning and personal autonomy. Though long viewed through anthropological lenses, modern psychiatry recognizes its overlap with neuropsychiatric and...
Language Disorder: Developmental Delays, Acquired Aphasia, and Best Treatment Practices
Language Disorder encompasses a range of developmental and acquired impairments in comprehension and/or use of spoken, written, and nonverbal communication. Affecting children and adults alike, it interferes with social interaction, academic achievement, and occupational functioning.

Lack of Empathy Disorder: Diagnosis, Behavioral Indicators, Risk Factors, and Intervention Strategies
Lack of Empathy Disorder is a pattern of persistent difficulty understanding or sharing others’ emotional experiences, leading to impaired relationships and social functioning. Although “disorder” in the strict DSM-5 sense may not yet apply, emerging research highlights clinically significant presentations—often overlapping with personality, neurodevelopmental, or neurocognitive conditions—where empathy deficits cause distress, conflict, and isolation. Recognizing when normal variability in...
Korsakoff Syndrome: Thiamine Deficiency, Cognitive Deficits, and Treatment Pathways
Korsakoff Syndrome is a chronic memory disorder most often resulting from severe thiamine (vitamin B₁) deficiency, commonly seen in individuals with prolonged alcohol misuse. Characterized by profound anterograde amnesia, confabulation, and executive dysfunction, it profoundly disrupts daily living and interpersonal relationships. Often preceded by Wernicke encephalopathy’s acute triad—ophthalmoplegia, ataxia, and confusion—Korsakoff Syndrome cements long-term cognitive deficits when not promptly...
Koro Syndrome: Diagnosis, Epidemic Dynamics, and Management Strategies
Koro Syndrome is a culture-bound somatic delusion characterized by an overpowering fear that one’s genitals (or breasts in women) are retracting into the body and that this will lead to death. Though rare globally, outbreaks—particularly in Southeast Asia—have highlighted its acute, panic-driven nature and intense distress. Episodes can occur individually or in epidemics, often precipitated by anxiety, social pressures,...
Kluver-Bucy Syndrome: Risk Factors, Diagnostic Workup, and Therapeutic Strategies
Kluver-Bucy Syndrome is a rare neurobehavioral disorder arising from bilateral damage to the medial temporal lobes—including the amygdala and hippocampus—often due to encephalitis, trauma, or surgical resection. It manifests as a unique constellation of symptoms: hyperorality (compulsion to examine objects by mouth), hypersexuality, visual agnosia (inability to recognize familiar objects or people), and placidity (diminished fear responses). These profound...
Kleptomania: Risk Reduction, Family Support, and Long-Term Relapse Prevention
Kleptomania is a psychiatric impulse-control disorder characterized by recurrent, irresistible urges to steal items not needed for personal use or monetary value.
