What is Cognitive Testing?
Cognitive tests are assessment tools used to measure various aspects of cognitive function, including memory, attention, executive function, and language skills. These tests are designed to evaluate an individual’s cognitive abilities and provide insights into their cognitive health and performance.
Cognitive tests provide direct behavioural measures of cognitive function, offering complementary information
to neuroimaging data.
While techniques such as EEG or TMS can reveal functional changes in the brain, cognitive tests help assess how these changes manifest in terms of cognitive abilities and everyday functioning. This provides a holistic understanding of the drug’s effects on the brain and behaviour.
Cognitive tests serve as sensitive indicators of drug efficacy or potential sides effects. By monitoring these changes in cognitive performance over the course of a clinical trial, researchers can evaluate the impact of the experimental drug on cognitive function. This comprehensive approach allows for a more thorough assessment of the drugs effects on both brain function and cognitive performance, enhancing the validity and reliability of the trial results.

What is Physiological Testing?
Our physiological tests assess various bodily functions and systems, such as visuomotor coordination, pupil dilation and posturography, to understand overall health and well-being. We are also able to offer cerebrospinal fluid (CSF) sampling for biomarker analysis and safety monitoring. Electromyography (EMG) can also be utilised as a marker of treatment response, by measuring changes in muscle activity or muscle tone in response to the drug.
Physiological tests offer complementary information to neuroimaging data, providing a broader understanding of the drug’s effects on physiological response. By integrating these methods, researchers can better assess
the drug’s impact.
Physiological tests serve as important safety measures to monitor potential adverse effects of the drug on normal bodily functions. By regularly assessing these parameters throughout the trial, any abnormalities or adverse reactions can be detected early on.
Integrating physiological tests with neuroimaging enhances trial reliability and validity. By assessing the drug’s effects on multiple physiological domains, researchers gain a comprehensive understanding of its overall impact, facilitating informed clinical decision-making.
