A new study published in the journal of neurology suggests that the length of our arms and legs raise the risk of memory loss.

According to the report, the women with the shortest arm spans were 50 percent more likely to develop dementia and Alzheimer's disease than women with longer arm spans. And the longer a woman's leg from floor to knee, the lower her risk for dementia. While in men, only a shorter arm span was linked with higher dementia risk.

If your body type does fall into this category, fear not. Another experiment that implants electrodes in your brain has been proven to reverse memory loss.

The electrodes are implanted under local anaesthesia while the patient is awake. Before the operation, the neurosurgeon performs an MRI scan and establishes the target location for the electrodes. He then carries out a craniotomy – lifting a section of the skull – and inserts the electrodes and leads.

During the experiment, the patient recalled a scene from 30 years earlier. More tests showed his ability to learn was dramatically improved when the current was switched on and his brain stimulated.
