656 Possible Causes for Developmental Regression

  • Neuronal Ceroid Lipofuscinosis

    A patient presented with rapid developmental regression whose MRI findings suggested a leukodystrophy, but nerve, muscle, skin, and bone marrow biopsies were unrevealing.[ncbi.nlm.nih.gov] A 4-year-old male presented with a 2-year history of epilepsy and progressive developmental regression.[ncbi.nlm.nih.gov] A 4-year-old boy presented with intractable epilepsy and developmental regression starting 1 year previously.[ncbi.nlm.nih.gov]

  • Vitamin B12 Deficiency

    Severe vitamin B(12) deficiency produces a cluster of neurological symptoms in infants, including irritability, failure to thrive, apathy, anorexia, and developmental regression[ncbi.nlm.nih.gov] Three months later, developmental regression and failure to thrive led to the diagnosis of vitB(12) deficiency, as a consequence of a subclinical pernicious anaemia with vitB[ncbi.nlm.nih.gov] These patients can present with unexpected signs and symptoms, such as developmental delay and regression as in our patient.[ncbi.nlm.nih.gov]

  • Kohlschütter-Tönz Syndrome

    Kohlschutter-tonz syndrome (KTS) is a rare neurodegenerative disorder that presents with seizures, developmental regression, characteristic hypoplastic dental enamel indicative[ncbi.nlm.nih.gov] regression and characteristic hypoplastic dental enamel indicative of amelogenesis imperfecta besides dysmorphologies.[otorhinolaryngologysfakianakisal.blogspot.com] regression.[xpertdox.com]

  • West Syndrome

    None of the patients showed developmental regression following surgery.[ncbi.nlm.nih.gov] Here, we report a one-year, six-month-old girl with complex partial seizures who developed infantile spasms, developmental regression, and hypsarrhythmia during the two weeks[ncbi.nlm.nih.gov] regression.[ncbi.nlm.nih.gov]

  • Alpers Syndrome

    All patients manifested developmental delay or regression, refractory epilepsy, and biochemical liver dysfunction.[ncbi.nlm.nih.gov] Dementia is typically episodic, and unremitting seizures may contribute to developmental regression as well.[secure.ssa.gov] Seizures may be difficult to control and unrelenting seizures can cause developmental regression as well.[ninds.nih.gov]

  • Peripheral Neuropathy

    We describe a consanguineous girl exhibiting severe developmental regression, intractable epilepsy, polyneuropathy, and profound hypomyelination with cortical involvement.[ncbi.nlm.nih.gov] It is characterized by late infantile onset, severe psychomotor regression, epilepsy, and leukodystrophy.[ncbi.nlm.nih.gov]

  • Childhood Disintegrative Disorder

    The occurrence of developmental regression in autism is one of the more puzzling features of this disorder.[ncbi.nlm.nih.gov] Abstract The occurrence of developmental regression in autism is one of the more puzzling features of this disorder.[doi.org] The condition is characterized by sudden onset and severe developmental regression between 3 and 5 years of age after previously normal development.[eric.ed.gov]

    Global developmental delay and developmental regression, David Michelson, MD and Stephen Ashwal, MD 08.[worldcat.org]

  • Cardiomyopathy

    CASE: A 6-month-old girl with no remarkable family or past medical history until 1 month prior presented with developmental regression and feeding impairment.[ncbi.nlm.nih.gov]
