Epilepsy and Seizures: Overview

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Satellite Stem Cells and Muscular Dystrophy

Satellite Stem Cells and Muscular Dystrophy

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Epilepsy ll: Types

Epilepsy ll: Types

Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.

Sex-linked Disorders

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Disorders of the Skeletal Muscle

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Huntington Disease l: Introduction

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Summary

Epilepsy affects 6.3% of Duchenne muscular dystrophy (DMD) patients, a higher rate than in the general pediatric population. This study found epilepsy risk does not increase with intellectual disability in DMD boys.

Background:

Duchenne muscular dystrophy (DMD) is associated with cognitive and behavioral challenges in about one-third of patients.
Epilepsy is a significant concern in neurological disorders, requiring accurate prevalence data.

Purpose of the Study:

To determine the prevalence of epilepsy in a cohort of 222 Duchenne muscular dystrophy patients.
To analyze seizure types, age of onset, and the relationship between epilepsy and intellectual disability in DMD.

Main Methods:

A cohort of 222 Duchenne muscular dystrophy patients was assessed for epilepsy.
Seizure types, age of onset, and intellectual quotient (IQ) were recorded.
Electroencephalogram (EEG) was used to confirm epilepsy in ambiguous cases.

Main Results:

Epilepsy was diagnosed in 14 out of 222 DMD patients (6.3%).
The mean age of seizure onset was 7.8 years, with seizure types including focal, generalized tonic-clonic, and absence seizures.
Epilepsy prevalence was 8.1% in DMD patients with normal IQ and 2.7% in those with mental retardation.

Conclusions:

The prevalence of epilepsy in Duchenne muscular dystrophy patients is higher than in the general pediatric population.
Epilepsy risk does not appear to be elevated in DMD patients with mental retardation.
Early identification and management of epilepsy are crucial in DMD care.
