Abstract
Treatment initiated 3 days after stroke significantly improved motor outcomes and reduced brain lesion volume in mice.
- The small-molecule clock modulator KL001 and high-dose melatonin enhanced glymphatic function in mice.
- Acute light pulses and active-phase time-restricted feeding also improved glymphatic function.
- Initiating KL001 or time-restricted feeding after stroke led to increased glymphatic flow.
- Poststroke brain cytokine levels were lowered with these interventions, indicating reduced inflammation.
- Reinforcing normal daily rhythms could enhance neurological recovery following a stroke.
