Decoding the Clinical Features that Associate with Progression, Causes, and Outcomes in Patients with Suspected...

Area of Science:

• Neurology
• Neuroscience
• Clinical Medicine

Background:

• Rapidly progressive dementia (RPD) presents a diagnostic challenge.
• Identifying early clinical features is crucial for timely diagnosis and management.

Purpose of the Study:

• To identify clinical features that predict the development of RPD in patients with suspected cases.
• To improve diagnostic accuracy and prognostic assessment for RPD.

Main Methods:

• A cohort of 248 patients with suspected RPD was analyzed retrospectively.
• Clinical data were reviewed by dementia specialists to diagnose RPD based on specific timelines of dementia onset or incapacitation.
• Univariate and multivariate analyses explored associations between clinical features and RPD diagnosis.

Main Results:

• 185 patients (74.6%) met RPD criteria. RPD patients were older and more frequently diagnosed with Alzheimer's disease or Creutzfeldt-Jakob disease.
• Specific features like visual agnosia, brain atrophy, and epileptiform discharges were exclusively found in RPD patients.
• Factors independently associated with RPD included intensive care unit admission, lack of seizures, abnormal MRI, and low CSF white blood cell count.

Conclusions:

• Clinical features can effectively identify patients likely to develop RPD.
• Early recognition of these indicators aids in accurate diagnosis and prognosis.
• This study provides valuable insights for clinicians managing suspected RPD cases.
