A neglected area in the management of chronic kidney disease (CKD) and hemodialysis (HD) is the early detection and amelior- ation of cognitive decline. A survey of the literature indicates that in patients with CKD, there is a high prevalence of cognitive and neurological impairments, where approximately 70% of HD patients age 55 and older suffer from moderate to severe chronic cognitive dysfunction (1,2).

impairment may manifest as difficulty in recall, confusion and dementia (2).
Although the exact cause for the decline is unknown, several factors such as vascular disease and inflammation, progression of CKD, hemodialysis, and increase stroke prevalence could contribute to its development (3). Furthermore, uremic neurotoxins, such as creatinine and guanidine, accumulate during CKD progression (4-7). With the largely growing incidence of neurological deficits in HD patients, there is a compelling need for high-throughput screening biomarkers to diagnose, monitor, and evaluate protective measures aimed at ameliorating cognitive decline. One area that has shown promising results is the capitalization on the immune system to indicate nervous system (NS) damage in the form of neuro- auto- antibodies, or neuroantibodies.
Capitalizing on the Immune System to Detect Nervous System Damage
The identification of autoantibodies as potential biomarkers of NS insult arose based upon the premise that neurodegeneration results in the loss of NS-specific proteins.
To these proteins, the immune system mounts a humoral immune response which can be detected in blood (8).The loss of NS proteins to the periphery has been reported in numerous neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and depression (9-11). Whereas these proteins have limited half-lives in cerebral spinal fluid and serum, the Furthermore, uremic neurotoxins, such as creatinine and guanidine, accumulate during CKD progression (4-7). With the largely growing incidence of neurological deficits in HD patients, there is a compelling need for high-throughput screening biomarkers to diagnose, monitor, and evaluate protective measures aimed at ameliorating cognitive decline.
