Brain health is becoming an increasingly important part of healthcare as neurological disorders, cognitive decline, and age-related conditions affect more people around the world. At the same time, healthcare providers are looking for better ways to identify changes in memory, attention, and cognitive function at an earlier stage.
The global cognitive assessment and brain health sector was valued at USD 9.40 billion in 2025 and is projected to reach approximately USD 28.69 billion by 2035, expanding at a CAGR of 11.80% from 2026 to 2035.
The growth is being supported by rising neurological disease prevalence, greater awareness of brain health, expanding digital healthcare, advances in artificial intelligence, and increasing demand for early cognitive assessment.

Why Cognitive Assessment and Brain Health Are Becoming More Important
Cognitive assessment involves structured tests designed to evaluate functions such as memory, attention, reasoning, language, and problem-solving.
These assessments can help healthcare professionals understand changes in cognitive function and identify individuals who may require further neurological evaluation.
Brain health extends beyond memory alone. It includes cognitive, emotional, behavioral, sensory, and motor functions that contribute to a person’s ability to live independently and maintain quality of life.
As populations age, the need for accessible and repeatable cognitive assessment is increasing. Alzheimer’s disease, dementia, traumatic brain injuries, mental health conditions, and other neurological disorders are encouraging healthcare providers to focus more strongly on early detection and ongoing monitoring.
AI Is Changing Cognitive Assessment
Artificial intelligence is becoming one of the most important technologies in the cognitive assessment and brain health sector.
Traditional cognitive assessments can be time-consuming and may depend heavily on clinical interpretation. AI-enabled tools can analyze large datasets and identify patterns across cognitive tests, medical records, brain imaging, speech, movement, and other digital biomarkers.
Machine learning can support earlier identification of subtle changes that may otherwise be difficult to detect through a single clinical assessment.
AI can also personalize assessments by adapting questions or testing difficulty based on an individual’s responses.
Another important development is the use of smartphones, smartwatches, and wearable technologies. These devices can collect behavioral and physiological information continuously, creating a more detailed picture of cognitive and functional health.
The future is likely to involve a combination of clinical assessments, AI analytics, digital biomarkers, and neuroimaging rather than relying on a single test.
Key Trends Shaping Cognitive Assessment and Brain Health
Digital Cognitive Assessments Are Becoming More Accessible
Digital cognitive assessment platforms accounted for 46% of the technology category in 2025.
These platforms allow assessments to be performed using computers, tablets, and smartphones, making testing more convenient for hospitals, clinics, research organizations, and patients.
Digital systems can also make it easier to repeat assessments over time and compare changes in cognitive performance.
This is particularly valuable for neurological conditions where tracking progression is just as important as obtaining a single baseline measurement.
AI-Based Cognitive Analytics Are Growing Rapidly
AI-based cognitive analytics represented 19% in 2025 and are expected to grow at a 17.2% CAGR from 2026 to 2035.
AI can process large volumes of cognitive and behavioral information and identify relationships that may be difficult to recognize manually.
For researchers, these capabilities can support patient stratification, clinical trial analysis, and digital endpoint development.
For healthcare providers, AI can potentially assist in prioritizing patients who may benefit from additional evaluation.
Remote Cognitive Assessment Is Expanding
Cognitive testing is increasingly moving beyond hospitals and clinics.
Smartphones, tablets, wearables, and remote healthcare platforms allow some assessments to take place at home.
This can be particularly useful for older adults, patients with mobility challenges, and people living in areas with limited access to neurological specialists.
Remote testing also allows repeated measurements, which may provide a better understanding of gradual cognitive changes.
Multimodal Assessment Is Becoming the Future
One of the strongest emerging trends is combining multiple forms of information.
AI-based cognitive tests can be combined with blood-based biomarkers, MRI or PET imaging, wearable information, and patient history.
Rather than relying on a single data source, multimodal approaches can provide a broader view of brain health and may improve assessment accuracy.

Smart devices can capture data related to sleep, movement, heart rate, activity, and other physiological signals.
When analyzed over time, these measurements may help researchers understand relationships between lifestyle, sleep, stress, physical activity, and cognitive performance.
Wearables are also making continuous monitoring more practical. Instead of assessing cognitive health only during occasional visits, digital technologies can provide information from everyday life.
The challenge is turning this continuous data into clinically meaningful insights while maintaining privacy, accuracy, and user engagement.
Challenges Facing Cognitive Assessment
Despite rapid technological progress, several challenges remain.
Data privacy is a major concern because digital cognitive platforms collect sensitive health information.
High subscription, licensing, and technology costs can also limit adoption, particularly in healthcare systems with restricted budgets.
Another challenge is validation. Digital cognitive assessments must demonstrate that their results are reliable, repeatable, and clinically meaningful.
Healthcare professionals also need clear guidance on how AI-generated insights should be incorporated into clinical decisions.
The technology should support clinicians rather than replace professional evaluation.
What Should Healthcare Companies Watch?
Healthcare providers, pharmaceutical companies, biotechnology firms, digital health companies, and investors should closely monitor:
- AI-based cognitive analytics
- Digital cognitive assessments
- Remote brain health monitoring
- Memory assessment technologies
- Wearable brain monitoring

What Comes Next?
Cognitive assessment and brain health are moving toward a more digital, continuous, and personalized model of care.
The traditional approach of conducting occasional cognitive testing is gradually being supported by digital platforms that can collect information more frequently and in real-world environments.
AI will be particularly important in this transition. It can help analyze complex datasets, identify patterns, and support earlier recognition of potential cognitive changes.
The most promising future may come from combining cognitive assessments, AI, biomarkers, neuroimaging, wearable devices, and clinical expertise.
The goal is not simply to detect cognitive decline. It is to understand changes earlier, monitor them more effectively, and provide individuals with personalized guidance throughout their brain health journey.
As neurological disorders become a larger healthcare challenge, cognitive assessment technologies could become an increasingly important part of preventive healthcare, clinical research, and long-term patient management.
