The goal of this clinical trial is to test the effects of aerobic exercise and BDNF on patients with ischemic and hemorrhagic stroke during a computerized cognitive training.

The main questions it aims to answer are:

1. Does a moderate intensity aerobic exercise, prior to a cognitive training, allow a better performance?
2. Is it possible to exploit the timing of rehabilitation interventions to obtain greater effects? Participants will be divided in 2 groups. The experimental group will first perform 20 minutes of pedaling as a moderate intensity aerobic exercise. It will then participate in one-hour cognitive training sessions, with the aim of training attentional, working memory and executive functions. The control group will carry out the same interventions but in reverse order.

The researchers will compare the results of the cognitive training in the two groups to verify if the order of the interventions influences the results themselves.

Inclusion Criteria:

• Patients with a clinical diagnosis of stroke, both ischemic and haemorrhagic.
