Abstract

Background

ParkWest is a large Norwegian multicenter study of newly diagnosed drug-naïve subjects with Parkinson’s disease (PD). Cognitively normal PD subjects (PDCN) and PD subjects with mild cognitive impairment (PDMCI) from this cohort have significant hippocampal atrophy and ventricular enlargement compared to normal controls. Here we aimed to investigate whether the same structural changes are associated with CSF levels of Aβ₃₈, Aβ₄₀, Aβ₄₂, total tau and phosphorylated tau.

Methods

We performed 3D radial distance analyses of the hippocampi and lateral ventricles using the MRI data from ParkWest subjects who provided CSF at baseline. Our sample consisted of 73 PDCN and 18 PDMCI subjects.

Results

We found significant associations between the levels of all three CSF Aβ analytes and t-tau and lateral ventricular enlargement in the pooled sample. In the PDCN sample all three amyloid analytesshowed significant associations with the radial distance of the occipital and frontal horns of the lateral ventricles. CSF Aβ₃₈ and Aβ₄₂ showed negative associations with enlargement in occipital and frontal horns of the lateral ventricles in the pooled sample, and a negative association with the occipital horns in PDMCI.

Conclusion

CSF Aβ levels in early PD correlate with ventricular enlargement, previously associated with PDD. CSF and MRI markers may therefore help identify PD patients at high risk for developing cognitive decline and dementia in the course of their illness. Contrary to Alzheimer’s disease, we found no associations between CSF t-tau and p-tau and hippocampal atrophy.

<p id="P1">ParkWest is a large Norwegian multicenter study of newly diagnosed drug-naïve subjects with Parkinson’s disease (PD). Cognitively normal PD subjects (PDCN) and PD subjects with mild cognitive impairment (PDMCI) from this cohort have significant hippocampal atrophy and ventricular enlargement compared to normal controls. Here we aimed to investigate whether the same structural changes are associated with CSF levels of Aβ<sub>38</sub>
, Aβ<sub>40</sub>
, Aβ<sub>42</sub>
, total tau and phosphorylated tau.</p>
</sec>
<sec id="S2"><title>Methods</title>
<p id="P2">We performed 3D radial distance analyses of the hippocampi and lateral ventricles using the MRI data from ParkWest subjects who provided CSF at baseline. Our sample consisted of 73 PDCN and 18 PDMCI subjects.</p>
</sec>
<sec id="S3"><title>Results</title>
<p id="P3">We found significant associations between the levels of all three CSF Aβ analytes and t-tau and lateral ventricular enlargement in the pooled sample. In the PDCN sample all three amyloid analytesshowed significant associations with the radial distance of the occipital and frontal horns of the lateral ventricles. CSF Aβ<sub>38</sub>
 and Aβ<sub>42</sub>
 showed negative associations with enlargement in occipital and frontal horns of the lateral ventricles in the pooled sample, and a negative association with the occipital horns in PDMCI.</p>
</sec>
<sec id="S4"><title>Conclusion</title>
<p id="P4">CSF Aβ levels in early PD correlate with ventricular enlargement, previously associated with PDD. CSF and MRI markers may therefore help identify PD patients at high risk for developing cognitive decline and dementia in the course of their illness. Contrary to Alzheimer’s disease, we found no associations between CSF t-tau and p-tau and hippocampal atrophy.</p>
