Why we age

open access: yesBiological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Patient and caregiver perspectives on burden of disease manifestations in late-onset Tay-Sachs and Sandhoff diseases

open access: yesOrphanet Journal of Rare Diseases, 2020
Background The GM2 gangliosidoses (GM2), Tay-Sachs and Sandhoff diseases, are rare, autosomal recessive genetic disorders caused by mutations in the lysosomal enzyme β-hexosaminidase A (HEXA) or β-hexosaminidase B (HEXB) genes, respectively.

Diagnostic Dilemma in an Infant With Sound‐Triggered Motor Events: Reflex Epilepsy Versus Exaggerated Startle—A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Auditory‐triggered motor events in infancy present a significant diagnostic challenge due to overlap between epileptic and non‐epileptic startle phenomena. We report the case of a term female infant with neonatal‐onset seizures and subsequent development of reproducible sound‐triggered jerky movements, raising diagnostic uncertainty between ...

Alkaline Phosphatase and Infantile GM1 Gangliosidosis: A Simple Biomarker for a Complex Disease?

open access: yesJIMD Reports, Volume 67, Issue 2, March 2026.
ABSTRACT GM1 gangliosidosis is a lysosomal storage disease (LSD) caused by β‐galactosidase deficiency, characterized by the accumulation of gangliosides in various tissues. Among different GM1 forms (infantile form, late‐infantile and juvenile form, and late‐onset form), the infantile form is the most severe: despite an early clinical onset with rapid ...

Generalized accumulation of neutral glycosphingolipids with GM2 ganglioside accumulation in the brain

open access: yesJournal of Lipid Research, 1972
Analyses have been made of glycosphingolipids from visceral organs and brain of a patient with an unusual lipid storage disorder diagnosed initially as classical Tay-Sachs disease. Levels of the lipids from fresh-frozen sections of gray and white matter,

Characterization of inducible models of Tay-Sachs and related disease. [PDF]

open access: yesPLoS Genetics, 2012
Tay-Sachs and Sandhoff diseases are lethal inborn errors of acid β-N-acetylhexosaminidase activity, characterized by lysosomal storage of GM2 ganglioside and related glycoconjugates in the nervous system.
