Dementia Care Research and Psychosocial Factors

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Alzheimer's disease (AD) involves cognitive decline, amyloid-beta plaques, and tau tangles.
• Deregulation of lipid metabolism, oxidative stress, and neuroinflammation are key factors in AD.
• Experimental models are crucial for understanding AD pathophysiology and testing therapeutics.

Purpose of the Study:

• To investigate the neuroprotective potential of Fingolimod (FTY720) in a rat model of sporadic dementia.
• To evaluate Fingolimod's effects on cognitive function, oxidative stress, and neuronal integrity.

Main Methods:

• Induced experimental dementia in rats using intracerebroventricular colchicine (ICV-COL).
• Administered Fingolimod (0.25 and 0.5 mg/kg) on alternate days.
• Assessed spatial and non-spatial memory using the Morris water maze and object recognition test.
• Measured oxidative stress markers (malondialdehyde, reduced glutathione, catalase) in hippocampus and cortex.
• Evaluated neurodegeneration via histopathological examination.

Main Results:

• ICV-COL infusion induced significant cognitive deficits and increased oxidative stress markers.
• Fingolimod treatment attenuated colchicine-induced cognitive decline.
• Fingolimod reduced oxidative burden and preserved neuronal architecture in the hippocampus and cortex.
• Histopathological examination confirmed reduced neurodegeneration in Fingolimod-treated rats.

Conclusions:

• Fingolimod exhibits significant neuroprotective potential against ICV-COL-induced dementia.
• FTY720 effectively mitigates cognitive deficits and oxidative stress in this model.
• Fingolimod suggests therapeutic promise for treating cognitive disorders like Alzheimer's disease.
