Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Smooth Endoplasmic Reticulum

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Oppositional Defiant Disorder

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
Diagnostic Criteria and...

Area of Science:

Neuroscience
Developmental Biology
Genetics

Background:

Rett syndrome is a rare neurodevelopmental disorder affecting early brain development.
It is characterized by normal early development followed by regression of skills.
The condition primarily impacts girls and is often associated with genetic mutations.

Observation:

A 5.5-year-old girl presented with a history of normal development until 17 months of age.
Following this period, she experienced developmental regression, losing acquired purposeful hand movements.
Stereotyped hand movements and epilepsy were observed as key clinical features.

Findings:

The case report details a unique presentation of Rett syndrome in a Bangladeshi child.
The patient exhibited classic symptoms including loss of hand skills and onset of seizures.
This represents the first documented case of Rett syndrome reported from Bangladesh.

Implications:

Increased physician awareness, particularly among pediatricians, is crucial for early Rett syndrome diagnosis.
Prompt diagnosis facilitates timely intervention and management strategies.
Reporting rare cases aids in understanding the global prevalence and presentation of Rett syndrome.
