Summary
Computed tomography revealed significant intracranial abnormalities in late dementia patients, with hydrocephalus and cortical atrophy being highly prevalent. This study assessed tomographic methods for cerebral morphometry in diagnosing these conditions.
Area of Science:
- Neurology
- Radiology
- Geriatrics
Background:
- Late dementia (LD) presents complex neurological challenges.
- Understanding intracranial pathology is crucial for managing dementia.
- Cerebral morphometry aids in diagnosing neurodegenerative conditions.
Purpose of the Study:
- To determine the prevalence of intracranial pathology in LD patients.
- To assess the rates of hydrocephalus (HDC) and cortical atrophy (CA) in LD.
- To compare the diagnostic value of tomographic methods in cerebral morphometry.
Main Methods:
- Computed tomography (CT) scans were analyzed.
- Data from 432 patients with LD were collected.
- Prevalence rates of pathologies, HDC, and CA were calculated.
Main Results:
- Intracranial abnormalities were found in 24.5% of LD patients, primarily postischemic foci.
- Tumors, cysts, and hematomas were less common (2.6%).
- HDC and CA were highly prevalent, detected in 81.5% and 82.2% of patients, respectively.
Conclusions:
- CT is valuable for identifying intracranial abnormalities in LD.
- HDC and CA are common findings in late dementia.
- Tomographic methods offer significant insights into cerebral morphometry for LD diagnosis.
