Abstract

CSF phospho-tau (p-tau(181)) levels have shown good diagnostic utility in differential diagnosis of Alzheimer disease (AD). Unlike total-tau (t-tau), age related changes of this promising biomarker are sparsely studied. The aim of the study was to determine whether p-tau(181) is dependent on age, cognitive status or gender in patients with different neurological diseases who underwent diagnostic lumbar puncture and who had no clinical evidence of neurodegenerative diseases. CSF levels of p-tau(181) and total-tau (t-tau) of 46 neurologic patients (age range 22-89 years; 22 male, 24 female) were analyzed. Clinical diagnoses were cerebral ischaemia (n = 6), multiple sclerosis (n = 13), epileptic seizures (n = 3), polyneuropathy (n = 9) and other neurological diagnoses (n = 15). Cognitive performance was assessed by the German version of the CERAD battery. The mean level of p-tau(181) was in accordance with previous findings in neurological patients (42.8 +/- 15.3 pg/ml) and did not differ between neurological diseases. In contrast to t-tau (r = 0.38; P = 0.009), p-tau(181) did not correlate significantly to age (r = 0.15; P = 0.308). No influence of cognitive status or gender on p-tau(181) levels could be detected. The study corro...Continue Reading

Alzheimer's Disease: Tau & TDP-43

Alzheimer's disease is a neurodegenerative disease. This feed focuses on the underlying role of tau proteins and TAR DNA-binding protein 43, as well as other genetic factors, in Alzheimer's disease.
