Many patients with Lewy body disease complain of pain, and their pain may be associated with this disease. Recently, pain has become a focus of attention in Parkinson's disease, but there is little information regarding pain in patients who have dementia with Lewy bodies. We used pregabalin to treat three Lewy body disease patients with chronic pain that may have been related to degeneration of central neurons. All three patients responded well to pregabalin at 25-50 mg/day. To our knowledge, there have been no previous reports of pregabalin showing efficacy for central neuropathic pain in Parkinson's disease or Lewy body disease.

This review highlights a collection of both diverse and highly impactful studies published in the previous year selected by the author from the neurodegenerative neuropathology literature. As with previous reviews in this series, the focus is, to the best of my ability, to highlight human tissue-based experimentation most relevant to experimental and clinical neuropathologists. A concerted effort was made to balance the selected studies across neurodegenerative disease categories, approaches, and methodologies to capture the breadth of the research landscape.

Introduction: Seed amplification assays (SAAs) demonstrate remarkable diagnostic performance in alpha-synucleinopathies. However, existing protocols lack accessibility in routine laboratories, mainly due to the requirement for in-house production of recombinant alpha-synuclein (aSyn). This study proposes a cerebrospinal fluid (CSF) aSyn-SAA protocol using solely commercial reagents to facilitate its clinical implementation.

The differential mechanisms between proteinopathies and neurodegeneration in Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) remain unclear. To address this issue, we conducted a voxel-based morphometry and cerebrospinal fluid biomarker (α-synuclein, Aβ42, t-Tau and p-Tau) level correlation study in patients with DLB, AD and mixed cases (AD + DLB). Cerebrospinal fluid samples obtained by lumbar puncture and whole-brain T1-weighted images were collected in the AlphaLewyMA cohort.

Aim: Despite the clinical importance and significant social burden of neuropsychiatric symptoms (NPS) in dementia, the underlying neurobiological mechanism remains poorly understood. Recently, neuroimaging-derived brain-age estimation by machine-learning analysis has shown promise as an individual-level biomarker. We investigated the relationship between NPS and brain-age in amnestic mild cognitive impairment (MCI) and early dementia.
