Assessment of mental stress, anxiety and depression from analysis of brain signals

Problem Statement: Mental stress, anxiety and depression are  mental health conditions that often occur together. In such a case, the person is stressed and is not able to control the worry, and it correspondingly affects his/her social and occupational activities. Hence, proper assessment and diagnosis for mental stress, anxiety and depression is required in order for a person to effectively keep taking part in his/her normal daily tasks and activities.

Issues with Current Solutions: Unfortunately, conventional assessment and diagnostic measures are subjective in nature and are used only when the symptoms are already evident due to advanced stages of mental stress, anxiety and depression. However, mental stress, anxiety and depression do not occur overnight, rather it is a long process. Hence, detection of symptoms is required at early stages of mental stress, anxiety and depression because that may result in a cure or at least it will delay the onset of serious mental health issues associated with them.

Challenges: Unlike other diseases where the symptoms like fever and cough allow people to seek help, symptoms at early stages of mental stress and anxiety are not easily identifiable. Hence, the brain needs to be continuously monitored for any sign of change or deterioration in order to detect the symptoms at early stage.

Solution: The solution lies in the development of an objective and quantitative method that can detect mental stress, anxiety and depression at an early stage. Perception of mental stress, anxiety and depression originates in the brain; therefore, this research investigates the neurophysiological features extracted from brain electroencephalogram (EEG) signal to measure mental stress, anxiety and depression at early stage. This will require development of method for extraction of features as well as pattern recognition approach to provide a solution. The EEG dataset is already available for this project.

Few Words About Supervision: I have extensive experience of working in the field of neuro-signal and neuroimage processing and I am currently head of a research group in this area. This is a multidisciplinary project and it will involve working with clinicians. However, the core of the project is related to IT in terms of development of a new method.
