The diagnosis of neonatal/infantile Canavan disease relies on demonstration of very high concentration of N-acetylaspartic acid (NAA) in the urine. In mild/juvenile Canavan disease, NAA may only be slightly elevated; thus, the diagnosis relies on molecular genetic testing of ASPA , the gene encoding the enzyme aspartoacylase.
Canavan's disease is initially recognized by the appearance of symptoms, yet further examinations are needed for definitive diagnosis. Neuroimaging techniques such as Computed Tomography (CT) scan or Magnetic Resonance imaging (MRI) are typically used to detect the presence of degenerative subcortical white matter. [26]
Canavan disease is a less-studied type of leukodystrophy that, like MLD and Krabbe disease, is also inherited in an autosomal recessive pattern. It is due to a mutation in the ASPA gene that encodes aspartoacylase , an enzyme needed to metabolize N-acetyl-L-aspartate (NAA).
“Canavan disease is an extremely rare and rapidly progressive neurodegenerative disease that prevents most children from meeting basic developmental milestones, such as crawling, walking, speaking, and even holding their heads up. It is a terminal diagnosis with no approved treatment to date.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
