Patient Resources
Brain exercises, privately.
A small set of cognitive exercises built in-house by Raeven Health and curated by our clinicians. Each one targets a domain we assess in practice: processing speed, working memory, selective attention, and visual recall.
Recovery. Prevention. Optimization.
Built to protect your privacy
These exercises run entirely in your browser. There is no account, no sign-in, and no name or date of birth to enter. Nothing you do here is transmitted to Raeven Health, stored on our servers, or saved to your device, and no scores are added to your medical record. Close the tab and the session is gone. Because no identifiable health information is created or received, there is nothing here to expose.
We deliberately do not embed third-party training platforms such as commercial brain games, which require accounts and operate under their own privacy policies as independent services. If you choose to use one, do so directly with that company and review its terms. Anything you would like our clinicians to see should be discussed during a visit or through our secure channels, not typed into a public page.
Processing speed
Reaction Time
Wait for the panel to turn purple, then click as quickly as you can. Processing speed is one of the first domains affected after a concussion and one of the first to recover.
Best this session: —
Working memory
Digit Span
Hold a growing sequence of digits in mind and reproduce it. Working memory underpins conversation, reading comprehension, and everyday task-switching.
A sequence of digits will appear briefly. Type it back in order.
Longest span: —
Selective attention
Color and Word
Name the color of the ink rather than the word you read. This classic interference task exercises inhibitory control, the ability to suppress an automatic response.
Name the color of the ink, not the word itself.
Accuracy: —
Visual recall
Pattern Match
Turn over pairs and remember where each symbol sits. Visual-spatial memory supports navigation, recognition, and learning new environments.
Moves: 0
How to use these well
- Keep sessions short. Ten to fifteen minutes is plenty. If symptoms increase, stop and rest.
- Consistency beats intensity. Brief daily practice is more useful than an occasional long session.
- Context matters. Sleep, hydration, medication, and stress all move these results. A slow day is information, not a diagnosis.
These exercises are educational tools for general cognitive practice. They are not diagnostic tests, they do not measure or screen for any medical condition, and they are not a substitute for formal neurocognitive testing or medical advice from your clinician.
