Conditions such as colour blindness, seasonal affective disorder, alcoholism, attention deficit disorder, dyslexia, obesity, autism, synesthesia, and even deja vu all have specific brain-to-body connections. This book provides insights into the symptoms, causes, and consequences of these abnormalities in their milder forms, as well as other health matters that statistically accompany each condition. Checklists and testing exercises used for professional diagnosis of these cognitive abnormalities are provided, as are probable causes and consequences of each.
