Insights

Tuberous sclerosis (TS) in children with infantile spasms leads to poor long-term outcomes, including intractable epilepsy and developmental delays. Early diagnosis of TS is crucial for prognosis and managing treatment, especially with ACTH therapy.

Area of Science:

  • Neurology
  • Pediatrics
  • Genetics

Background:

  • Tuberous sclerosis (TS) is a genetic disorder that can affect multiple organs.
  • Infantile spasms are a severe form of epilepsy in infants.
  • The co-occurrence of TS and infantile spasms presents unique diagnostic and prognostic challenges.

Purpose of the Study:

  • To investigate the short- and long-term outcomes for children diagnosed with both infantile spasms and tuberous sclerosis.
  • To highlight the diagnostic difficulties and characteristic manifestations of TS in this patient group.
  • To compare the prognosis of these children with those having idiopathic infantile spasms or other neurological disorders.

Main Methods:

  • Retrospective study of 24 children with infantile spasms and confirmed tuberous sclerosis.
  • Clinical examination focusing on characteristic TS features, particularly skin manifestations.
  • Neuroimaging (CT scans) to identify brain abnormalities.
  • Assessment of developmental, intellectual, and seizure outcomes.

Main Results:

  • TS diagnosis was often delayed, but characteristic skin findings and early brain abnormalities on CT scans were consistently present.
  • Associated TS manifestations included epilepsy, central nervous system tumors, cardiac rhabdomyomas, kidney disease, and retinal phakomas.
  • Long-term outcomes were poor: all children had impaired intelligence, and most experienced intractable epilepsy and behavioral problems.
  • Prognosis was significantly worse compared to children with idiopathic infantile spasms or other neurological comorbidities.

Conclusions:

  • Early diagnosis of tuberous sclerosis in infants with infantile spasms is vital for accurate prognosis.
  • Identifying TS can help avoid potential complications associated with treatments like ACTH therapy.
  • Children with TS and infantile spasms require specialized, long-term management due to the high likelihood of intractable epilepsy and developmental issues.

Autism Spectrum Disorder01:19

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.
Tetanus01:29

Tetanus

Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Huntington Disease l: Introduction01:21

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,...

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
