Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

649
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Depressive Disorders: MDD and Dysthymia

894
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Cardiomyopathy IV: Restrictive Cardiomyopathy

632
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Dissociative Identity Disorder

1.2K
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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

555
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

1.4K
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Duchenne Muscular Dystrophy (DMD) is a frequent childhood genetic disorder caused by dystrophin gene mutations.
  • DMD leads to the absence of full-length dystrophin protein, impacting muscle and central nervous system function.
  • Central nervous system involvement and epilepsy are known complications in DMD patients.

Observation:

  • The prevalence of epilepsy in DMD patients (6.3-12.3%) is significantly higher than in the general pediatric population (0.5-1%).
  • DMD patients can exhibit diverse seizure types, including focal, generalized tonic-clonic, and absence seizures.
  • This report details two boys with DMD presenting with epileptic spasms and hypsarrhythmia, meeting criteria for West syndrome.

Findings:

  • The study extends the spectrum of seizure types associated with Duchenne Muscular Dystrophy.
  • West syndrome, characterized by epileptic spasms and hypsarrhythmia, is identified in DMD patients.
  • This highlights a specific neurological manifestation within the broader central nervous system involvement in DMD.

Implications:

  • Recognizing West syndrome in DMD patients is crucial for timely diagnosis and management.
  • Further research into the neurobiological mechanisms linking dystrophin deficiency to specific epilepsy syndromes like West syndrome is warranted.
  • Understanding these associations can improve comprehensive care for children with Duchenne Muscular Dystrophy.
