Psychological Problems and their Solutions through Computer Techniques Presented By: Misbah Arif (0612117) Presentation Flow Introduction to Psychology Various Psychological Problems Computerized techniques in diagnosing Psychological Problems Importance in Pakistan Role of Bio-informatics Introduction to Psychology What is Psychology? Definition - Scientific study of behavior and mental processes It explores thoughts, emotions, feelings, sentiments, ideas, actions and behavior. Studies problems related to nervous system of our body Study of mind includes the study of mind in body and that leads the study of brain What is Psychology Brain – a Main player in Psychology Brain is the physical basis of our mind It directs the mind what to do and what not to do. Brain is always on the go and it is controlling almost every system of our body Little disturbance in brain affects entire body Diagrammatical representation of Brain Nervous System Neural Organization of Nervous System Nervous System acts like a network that communicates different messages back and forth from the brain to different parts and organs of the body. Types of Nervous System Central Nervous System Peripheral Nervous System Nervous System – cont.. Basic functioning of nervous system depends on billions of neurons that have many specialized jobs. Neurons establish a path with the help of neurotransmitters that help in traveling the microscopic gap known as synaptic cleft These connections become stronger as we grow older How Nervous System works? Various Psychological Problems Psychological Problems “Psychological problems are mental disorders or mental illness that occurs in an individual and is thought to cause distress or disability that is not expected as part of normal development or culture ” Stress Stress is anything that makes us feel upset or threatened in any way. Negative stress- Distress which can become a major cause of many other problems Causes – Work, family, unrealistic expectations etc Three different stages Stages of Stress Anxiety Long term distress can lead to anxiety An emotional state in which people feel uneasy, apprehensive or fearful “Anxiety occurs when a reaction is out of proportion with what might be normally expected in a situation.” Different symptoms of Anxiety Anxiety – cont.. Types of Anxiety Disorders Post-Traumatic Stress Disorder - anxiety that has resulted from any previous experience Generalized Anxiety Disorder – Unrealistic Social Anxiety Disorder - horror of being negatively judged by other people or a fear of public embarrassment cause of any reason Depression According to Robert J. Hedaya, "Depression is rapidly becoming the second leading cause of disability in the world.” PET Scan of Depressive and Normal Mind Depression – cont.. Symptoms of Depression ◦ Thinking ability will change ◦ Behave extremely rude due to their negative thoughts ◦ Appetite decreases ◦ Complain about every thing ◦ Excessive crying and lack of interest in physical appearance and hygiene Symptoms of Depression Computerized techniques in solving Psychological Problems Neuroimaging Psychological problem causes changes in the brain that can be viewed with brain imaging devices Neuroimaging - used to find the abnormality present in the structure of brain Helps in knowing the kind and level of problem occurred in brain MRI Scan PET Scan ECG of Mind Brain’s vestibular system is closely connected to the regions of the brain that are related to emotions and behavior. New technique that measures and compares the patterns and behavior of electrical activities in the brain’s balance or vestibular system ECG of Mind Computational Modeling A new tool for psychiatric medication development Realistic models of brain are developed Help a psychiatrist to examine brain at different levels and “what-if” scenarios MATLAB and General Neural Simulation System (GENESIS) Computational Modeling of Brain Importance in Pakistan and Role of Bioinformatics Importance in Pakistan Extreme importance Current Progress ◦ Pakistan Journal of Psychiatric society - an official journal of Pakistan Psychiatric Society. Journal of Pakistan Psychiatric Society ◦ Aga Khan and Liaquat National Hospital use different neuroimaging tools like FMRI and PET scan ◦ Various Conferences FMRI Scan of a patient taken at AKU in Pakistan Relationship with Bioinformatics Brain-informatics Brain-Informatics Used to understand causes of mental illness Solving major brain related problems with the help of technology Brain-Informatics Thank You!
