Cognitive Rehabilitation
in Calabasas
Think clearly. Remember reliably. Return to the work you know you can do.
Rebuilding mental sharpness after a concussion, a stroke, or another neurological setback should not feel like guesswork. Cognitive rehabilitation in Calabasas at California Brain & Spine Center is a structured, measured program built around attention, memory, and processing speed. Dr. Alireza Chizari, DC, DACNB, a board-certified chiropractic neurologist, starts by testing where the breakdown actually sits, then trains that system directly.
The quick, honest answer
Cognitive rehabilitation in 30 seconds
What it is
Training, not resting
Cognitive rehabilitation is a structured, therapist-guided program that trains attention, memory, processing speed, language, and executive skills through graded, repeatable exercise — the same principle as physical rehab, applied to thinking.
Who it may help
When thinking stopped being automatic
People recovering from concussion or traumatic brain injury, stroke, long COVID, or another neurological event — and those whose scans read "normal" while reading, planning, and remembering clearly are not back to normal.
Best next step
Measure before you train
Baseline testing across cognitive, oculomotor, and autonomic function shows which domain is actually limiting you. The program is then aimed at that domain and re-tested, rather than applied as a fixed protocol.
What we actually train
The six domains cognitive rehabilitation targets
Each is measured at baseline and re-measured as you progress. Improvement in one does not automatically mean improvement in another, which is why the testing matters.
Sustained Attention
Holding focus past the first ten minutes, and holding it in a room that is not quiet
Working Memory
Holding a phone number, an instruction, or a sentence in mind long enough to use it
Processing Speed
How long it takes to read, decide, and reply — the domain patients notice first at work
Executive Function
Planning a multi-step task, switching between them, and finishing what you started
Language & Word Finding
Sentences that stall mid-thought, or the right word arriving three seconds too late
Cognitive Endurance
Staying sharp through a full workday instead of collapsing after the first focused hour
Cognitive symptoms rarely arrive alone — see our brain fog treatment, memory loss treatment, and traumatic brain injury recovery programs.
Why conservative care
Most recovery happens after the acute phase
The majority of traumatic brain injuries are managed without surgery. What determines how well someone thinks a year later is usually what happens in the months of rehabilitation that follow, not the first 48 hours.
- Systematic reviews report improvements across attention, memory, and executive function after structured cognitive training, with the strongest signal in programs that are individualized and actively practised rather than passive
- Sessions run about 45 minutes and are built around work, classes, and family schedules rather than the reverse
- Chronic cases years past the original injury can still respond, because neuroplasticity is not limited to the first months
Finding the limiting system
Our six-step cognitive rehabilitation evaluation
Baseline scores set the goals and make every later session measurable. Dr. Chizari performs the evaluation himself before any program is written.
Detailed case history
Injury or illness timeline, work and study demands, sleep, medications. The story usually narrows the problem before any test runs.
Neuro-cognitive screening
Reaction time, processing speed, working memory, and executive-function tasks scored objectively rather than estimated from conversation.
Eye-tracking & oculomotor testing
Video oculography exposes unstable saccades and pursuit that make reading exhausting and are often mistaken for a memory problem.
Balance & postural sway
Objective balance metrics reveal how much processing capacity your brain is spending on staying upright instead of on thinking.
Autonomic & HRV assessment
Heart-rate variability and response to position change measure recovery reserve, a frequently missed limiter on cognitive endurance.
Goal mapping to real life
Targets are written against your actual roles, whether that is a full day of meetings in the Calabasas office parks or a semester of coursework.
Personalized care
What a cognitive rehabilitation program includes
Your plan draws on the components your findings point to. None of this is applied as a fixed protocol to everyone who walks in.
Is this right for you?
Who cognitive rehabilitation fits
You may be a good candidate if
- Thinking has not returned to baseline weeks after a concussion or brain injury
- Reading, spreadsheets, or long documents drain you far faster than they used to
- You lose the thread in meetings or in conversation in a noisy room
- You are recovering from a stroke and want structured cognitive work alongside medical care
- A student's grades, reading speed, or reaction times dropped after an injury
- Your scans and labs came back normal and no one has explained the symptoms
Most patients notice measurable change within 4–6 weeks of consistent training. Chronic and complex cases often take longer, and realistic timelines are set after your evaluation, not before it.
How progress is measured
- Objective re-testing — the same reaction-time and memory tasks repeated on a schedule, so change is a number rather than an impression
- Weekly review — plateaus trigger a change to the plan instead of more of the same
- Return-to-work and return-to-learn — load is raised deliberately, coordinated with employers, schools, and trainers
- Honest discharge — when the data stops moving and the goals are met, the program ends
Seek urgent medical care first for sudden weakness, slurred speech, seizure, vision loss, or a severe new headache. Those need emergency evaluation, not rehabilitation.
A patient story
"I could follow the meeting again"
Details changed to protect privacy. Representative of possible outcomes, not a guarantee of any specific result.
A 37-year-old finance manager from Woodland Hills came in eight months after a mild traumatic brain injury. Numbers were drifting off the spreadsheet, and a conversation in a busy room was impossible to hold onto. Testing pointed less to memory than to unstable eye movements and a low ceiling on cognitive endurance. Her program combined oculomotor work with graded computerized training and a strict load-management plan. Over about eight weeks her processing-speed scores climbed and she was running her own team meetings again, though longer days still needed pacing.
Progress is logged as data — reaction-time curves, error rates, endurance under load. Watching your own numbers move is both motivating and the only honest way to know the plan is working.
Common questions
Cognitive rehabilitation questions
How soon after an injury should cognitive rehabilitation start?
For mild injuries, within days to weeks once acute symptoms settle. Starting early tends to shorten recovery, but chronic cases years out still respond, because the brain's capacity to reorganize is not limited to the first few months after an injury.
Will the exercises make my symptoms worse?
Mild, short-lived fatigue or light-headedness during a session is common and usually signals productive neural effort. Intensity is titrated to keep sessions tolerable, and anything that provokes lasting symptoms is dialed back at the next visit rather than pushed through.
How many cognitive rehabilitation sessions will I need?
Most programs run several weeks with sessions around 45 minutes, supported by daily home work. The number depends on which domains are affected and how severe the original injury was. Re-testing determines when the program is finished, not a fixed session count.
Do children and teenagers qualify for cognitive rehabilitation in Calabasas?
Yes. Pediatric programs at our Calabasas clinic adjust workload to developmental stage and use gamified platforms to hold engagement. Return-to-learn planning is coordinated with the school so academic load rises in step with measured recovery.
Do I need a referral, and how does this fit with my other doctors?
No referral is needed for the initial evaluation. Dr. Chizari coordinates with your primary care provider, and with a medical neurologist or your stroke team where one is involved, so the program runs alongside your medical care rather than replacing it.
Retrain, don't wait
Stop waiting for the fog
to lift on its own.
If a concussion, a stroke, long COVID, or another neurological setback has left your thinking slower than it should be, the first step is measuring where the limit actually sits. Dr. Chizari provides non-surgical cognitive rehabilitation for patients across Calabasas, Woodland Hills, Agoura Hills, and the wider Los Angeles area. Call (818) 649-5300 or book online.
