Stimuli-responsive nanoscale drug delivery systems offer precise epilepsy treatment by targeting pathological changes. These smart systems enhance antiseizure drug efficacy for improved epilepsy theranostics.
Area of Science:
- Neurology
- Nanotechnology
- Biomedical Engineering
Background:
- Epilepsy is a neurological disorder with specific pathological changes in the epileptogenic zone.
- Antiseizure drugs (ASDs) are the primary treatment, but efficiency can be improved.
- Stimuli-responsive nanoscale drug delivery systems (nanoDDSs) offer a precise approach to epilepsy theranostics.
Purpose of the Study:
- To review pathological variations in epilepsy, including neurotransmitter systems, ion homeostasis, and inflammatory networks.
- To summarize recent advances in nanoDDSs activated by endogenous or exogenous stimuli.
- To discuss challenges and future prospects for stimuli-responsive nanoDDSs in epilepsy treatment.
Main Methods:
- Review of literature on epilepsy pathology and nanoDDSs.
- Categorization of nanoDDSs based on triggering stimuli (endogenous/exogenous).
- Analysis of pathological markers and their role in stimuli-responsive systems.
Main Results:
- Identified key pathological changes in epilepsy: neurotransmitter dysregulation, ion imbalance, and inflammation.
- Highlighted functional nano-assemblies responsive to endogenous (pathological) and exogenous (light, electricity) stimuli.
- Demonstrated the potential of nanoDDSs for spatial-temporal control of ASDs.
Conclusions:
- Stimuli-responsive nanoDDSs represent a promising strategy for precise and controllable epilepsy theranostics.
- Further development is needed to address challenges and establish generalized guidelines for smart nanoDDSs.
- These advanced systems hold potential for overcoming current limitations in epilepsy management.
