Vanishing White Matter Disease (VWMD), also known as Childhood Ataxia with Central Hypomyelination (CACH) is a leukoencephalopathy with an autosomal recessive inheritance. It is caused by mutations in any of the five genes encoding the five subunits of the eukaryotic translational initiation factor 2B (eIF2B). Although VWMD was initially described in young children, it is now well known that it has a wide phenotypic spectrum, affecting people of all ages.

VWMD is typically characterized by normal or mildly delayed initial psychomotor development, followed by episodic or chronic neurological deterioration, often provoked by infections or minor head trauma. Neurological signs consist mainly of cerebellar ataxia and spasticity. There is no specific treatment beside the “prevention” of cellular stress. Therefore, early recognition of the diagnosis is important to avoid triggering factors and allow genetic counseling.

The reported case describes the clinical and radiological characteristics of a patient with adulthood onset of VWMD, revealed by subcortical dementia.
