Drawing something that you want to remember is more effective than using other memory techniques.

Since drawing involves consideration of a thing from so many different angles (visual, spatial, semantic, and verbal) and also involves motor use, the brain stores a memory in more areas...

For older people with dementia or Alzheimer's, drawing stores memories in still-intact regions of the brain.

Drawing makes better use of brain regions that are still preserved, and could help people experiencing cognitive impairment with memory function.
