Cognition – Problems sequencing, memory, providing and maintaining attention, concentration, clarity and organization. Mood – Anger, sadness, explosiveness. Motor – Lack of grace, problems of eye-hand coordination, balance, increased muscle tone (from spasticity) and tremor. Motivation – Problems initiating tasks, shifting from one activity to another, and/or completing tasks. Anxiety – Problems of anxiety system activity (too much uncomfortably-contained energy), persistent “anxiety”, restlessness, rumination, agitation, distractibility, difficulty breathing, palpitations, tremor exacerbation, and sleep interruption. Reactivity – Hyper-reactivity, hypersensitivity, multiple chemical sensitivities. Pain – Brain-generated pain (mismapping the origins and qualities of signals), and vascular pain. Addictions/Dependencies – Lack of clarity about emotions and self-comforting, defensiveness, argumentativeness and cynicism. Fatigue – Fatigue; or fatigue as a phenomenon secondary to the effort of trying to overcome the pain and/or the above impediment to functioning more easily. Performance Optimization – Increases in functioning in the above areas in absence of any diagnosis. The LENS works well with symptoms of Central Nervous Symptom dysfunction. These include symptoms of ADD, ADHD, Seizures and sub-clinical seizure activity, severely disruptive behavior disorders such as Conduct Disorder, Reactive Attachment and Bipolar Disorder, Autistic spectrum and pervasive developmental delay, Cerebral palsy, concussive injuries, PTSD, Acquired Brain Injury, and Birth Trauma. The LENS works extremely well with the symptoms of Traumatic Brain Injury, no matter how long ago the incident occurred. The trauma can be from a physical blow, a concussive injury, a psychological incident (PTSD), or any other incident(s) which results in a decrease in cognitive ability. Many children have sleep problems that can be helped such as bed wetting, sleep walking, sleep talking, teeth grinding, nightmares, and night terrors. The LENS can also be helpful with many of the symptoms of adolescence including drug abuse, suicidal behavior, anxiety and depression. The LENS can also help in maintaining good brain function as people age.
