This research explores motor imagery as a rehabilitation tool after stroke. Brain imaging revealed sex-based differences in neural activation, with females showing greater efficiency. Practice improves patterns in both sexes. Understanding these differences enables personalized, home-based rehabilitation that may enhance recovery of arm and hand function.

Learning a new language, even later in life, can boost attention within a single week and support long-term cognitive resilience. Intensive language learners outperform peers in non-language courses, with benefits spanning ages 18–78. Practising five hours weekly maintains gains, offering a promising, accessible strategy for stroke recovery and dementia delay.
