Dementia is characterized by cognitive impairment and difficulties in executive functioning. It is an umbrella term for different subtypes that should be differentiated using a meticulous review of the patient's history, physical exam, and work-up. Posing difficulties in diagnosis, findings at times may be inconclusive. We report a case of a depressed patient on hemodialysis for end-stage renal disease (ESRD) who presents with an acute agitated episode following a visual hallucination that he has been experiencing intermittently for six months, along with a three- to four-year history of cognitive impairments. Our differential diagnosis includes vascular dementia, dementia with Lewy bodies, pseudodementia, dialysis dementia, and early-onset Alzheimer's. In this case, the findings of a normal mini-mental status exam (MMSE) and mental status exam (MSE) do not correlate with a working diagnosis. Due to persistent dilemmas in diagnosing early neurocognitive impairment, continued monitoring and re-assessment are necessitated for efficient management of psychiatric patients with cognitive decline.

Alzheimer's disease and diabetes-associated cognitive dysfunction: the microglia link?
Metab Brain Dis
January 2025
Department of Pharmacy, the Second Affiliated Hospital of Shaoyang University, Shaoyang, Hunan, China.
Alzheimer's disease (AD) is characterized by the accumulation of amyloid-β (Aβ) plaques and the aggregation of tau protein, resulting in intense memory loss and dementia. Diabetes-associated cognitive dysfunction (DACD) is a complication of diabetes mellitus, which is associated with decreased cognitive function and impaired memory. A growing body of literature emphasize the involvement of microglia in AD and DACD.

Methods: The experiment involved three groups: the control group, the POCD group and the POCD + EA group. The POCD animal model was established using sevoflurane anesthesia and tibial fracture.
Background: Postoperative cognitive dysfunction (POCD) is a postoperative complication of the central nervous system, especially in elderly patients. Growing evidence shows a close relationship between the kidney and cognition. This study aimed to evaluate the relationship between the subsequent risk of POCD and indicators related to the kidney.

Background: Effective treatment for Alzheimer's disease (AD) remains an unmet need. Thus, identifying patients with mild cognitive impairment (MCI) who are at high-risk of progressing to AD is crucial for early intervention.
Methods: Blood-based transcriptomics analyses were performed using a longitudinal study cohort to compare progressive MCI (P-MCI, n = 28), stable MCI (S-MCI, n = 39), and AD patients (n = 49).

Institute for Behavioral Medicine Research, Ohio State University, 460 Medical Center Drive, Columbus, OH, 43210, USA.
Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.
