Alzheimer's disease: cerebral glaucoma?

Wostyn, Peter, Audenaert, Kurt, De Deyn, Peter Paul·2010·Medical Hypotheses

Abstract

In a 1994 Medical Hypotheses paper, it was speculated that high intracranial pressure (ICP) might increase the probability of developing Alzheimer's disease (AD). A study of cerebrospinal fluid pressure (CSFP) in normal volunteers showed interindividual variations in CSFP. Some normals had what would normally be considered elevated CSFP. The hypothesis postulated that this subgroup with a high characteristic individual ICP level might be more susceptible to developing AD. The Medical Hypotheses paper further speculated that in more advanced stages of AD, such pressure factor could already be missing due to the disease process. The present article discusses recent research findings regarding CSFP distribution in AD patients that could be interpreted as support for this hypothesis. Exposure of central nervous system tissue to high pressure stress is not unique to the ICP space. Indeed, a similar situation occurs in the intraocular pressure (IOP) space in eyes with glaucoma. Interestingly, recent research has revealed similarities in the process leading to retinal ganglion cell death in glaucoma and neuronal cell death in AD. In the present paper, we raise the question of whether AD could be a cerebral form of glaucoma. Indeed, the linking of glaucoma to mechanisms of AD could reflect the anatomical and functional similarities between the IOP space and the ICP space. Further studies are warranted, however, especially to determine the possible role of high ICP in at least some cases of AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
