Insights
Stroke and dementia are increasing health burdens in the elderly. This review explores new treatments and research directions, highlighting functional MRI and central nervous system drug delivery challenges.
Area of Science:
- Neurology
- Geriatrics
- Pharmacology
Background:
- Stroke and dementia significantly impact the elderly population, with increasing prevalence due to aging demographics.
- Current therapeutic strategies for stroke and dementia are largely insufficient, hindered by challenges in translating preclinical findings to clinical practice.
Purpose of the Study:
- To review recent advancements in the pathophysiology and treatment of stroke and dementia.
- To discuss functional magnetic resonance imaging (fMRI) as a tool for assessing therapeutic effects and disease progression.
- To provide an overview of challenges and strategies in central nervous system drug delivery.
Main Methods:
- Literature review focusing on recent research in stroke and dementia.
- Detailed discussion of functional magnetic resonance imaging (fMRI) applications.
- Analysis of drug delivery methods for the central nervous system.
Main Results:
- Identified significant challenges in current stroke and dementia treatments.
- Highlighted the potential of fMRI in monitoring treatment efficacy and disease progression.
- Underscored the complexities of achieving effective drug delivery to the central nervous system.
Conclusions:
- There is a critical need for improved therapeutic interventions for stroke and dementia.
- Advanced imaging techniques like fMRI offer promising avenues for research and clinical monitoring.
- Overcoming central nervous system drug delivery barriers is crucial for developing effective treatments.
Abstract:
Stroke and dementia represent a major health burden for elderly subjects as they are associated with significant morbidity and mortality. The rates of stroke and dementia are progressively increasing due to the ageing population in most westernized countries. Therefore, both these conditions represent a major therapeutic target. However, the therapeutic options available for the management of stroke and dementia remain largely unsatisfactory, the main reason being the difficulty in transferring the results obtained in animal and in vitro studies to the clinical setting. This review focuses on the recent advances in pathophysiology and treatment of these conditions and future directions for research. Moreover, the technique of functional magnetic resonance imaging is discussed in detail as a tool to assess the effects of therapeutic agents on the central nervous system and monitor the progression of diseases. Finally, an overview of the issue of drug delivery into the central nervous system is presented.
