Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

97
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...

Prosopagnosia

402
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Cardiomyopathy II: Dilated Cardiomyopathy

84
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,...

Seizures: Classification01:13

Seizures: Classification

706
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Area of Science:

  • Neurology
  • Genetics

Background:

  • Hemiplegic migraine (HM) is a rare migraine subtype (0.01% prevalence) characterized by motor deficits (hemiparesis) and typical migraine aura symptoms.
  • Familial hemiplegic migraine (FHM) is diagnosed when first- or second-degree relatives also experience HM attacks.

Purpose of the Study:

  • To describe a family diagnosed with Familial Hemiplegic Migraine (FHM).
  • To review literature and discuss differential diagnosis aspects of FHM.

Main Methods:

  • Clinical case report.
  • Review of medical literature.

Main Results:

  • A father and daughter presented with severe headaches, nausea, vomiting, visual disturbances, speech impairment, and unilateral weakness/numbness.
  • The clinical presentation and family history led to a diagnosis of FHM.

Conclusions:

  • The described family case supports the diagnostic criteria for FHM.
  • Understanding FHM presentation is crucial for accurate diagnosis and management.
