Neurofeedback — also known as EEG Biofeedback — is an approach for treating ADHD in which individuals are provided real-time feedback on their brainwave activity and taught to alter their typical EEG pattern to one that is consistent with a focused and attentive state. According to neurofeedback proponents, this often results in improved attention and reduced hyperactive/impulsive behavior.
Several years ago I summarized the scientific support for neurofeedback treatment — see here - and noted that Read the rest of this entry »

Engaging people where they are in the life-course
Eighty percent of the 38,000 adults over age 50 who were responders in the 2010 AARP Member Opinion Survey indicated “staying mentally sharp” was their top ranked interest and concern (Dinger, 2010). What exactly does this phrase mean? And what role can technology play in “staying mentally sharp”? Intel CEO Paul Otellini has said, “You have to start by thinking about what people want to do… and work backward.” Read the rest of this entry »

The terminology “fundamental attribution error” describes the tendency to overvalue personality-based explanations for observed human behaviors, while undervaluing situational explanations for those behaviors. I believe that a primary reason behind many perceived and real ethical challenges in the brain fitness field is due not so much to certain stakeholders’ lack of personal or professional ethics, but derives from the flawed societal construct that underpins current, relevant innovations. To improve the ethics of the brain fitness business and its application (and empower consumers’ informed decision making), there must first be agreement about a meaningful, appropriate way to analyze and guide innovation. This is the crux of the problem. The current medical model is not up to the task at hand, since it is heavily skewed toward invasive drugs and devices driven by disease-based models, and fails to leverage Read the rest of this entry »

The recent discovery that experience can change brain structure and function at any age has sparked numerous health, education, and productivity applications whose value and limitations we are only starting to grasp.
Brain fitness has quickly become a mainstream aspiration among baby boomers and elders, primarily in North America. It has fueled a growing interest in brain fitness classes, brain fitness centers, and brain fitness programs, along with attendant opportunities and challenges. An increasing number of adults want useful tools to protect cognitive health and performance—not necessarily to reverse aging—and what they are finding is an expanding and noisy marketplace where they (and also professionals) need to carefully evaluate their own needs and the available options (Fernandez and Goldberg, 2009).

Many adults with ADHD do not obtain their diagnosis until adulthood and have struggled with difficulties related to undiagnosed ADHD for their entire lives. As documented in recent studies, this includes elevated rates of depression, anxiety disorders, substance use, work difficulties and interpersonal problems.
As with children and adolescents, medication treatment for adults with ADHD can be quite helpful, especially for reducing core ADHD symptoms of inattention and hyperactivity/impulsivity. However, Read the rest of this entry »

TO FIGHT, FLEE, OR FREEZE — THAT IS THE QUESTION
With a better understanding of the neurobiology of stress, the LD — ADHD — stress connection becomes clear. Students with learning disabilities or ADHD, confronted with the stress created by exposure to tasks that are in reality or in their perception too difficult (and thus threatening), exhibit the protective behavior of any organism under extreme stress: They fight, they flee, or they freeze. When these kids don’t understand why they can’t do what other kids can do (master the stressor), and they can’t see any way to get out of a situation that won’t go away, they begin to shut down.

The Human Brain Likes to Be in Balance
Fortunately, the brain has some built — in safety systems. Too much cortisol in the blood signals the brain and adrenal glands to decrease cortisol production. And under normal conditions, when the stress is overcome or brought under control (by fighting, fleeing, or turning into an immobile statue, or by mastering the threat), the hypothalamus starts sending out the orders to stand down. Stop producing cortisol! Event over! Under continuous stress, however, this feedback system breaks down. The hypothalamus keeps reading the stress as a threat, furtively sending messages to the pituitary gland, which screams out to the adrenal glands to keep pumping out cortisol, which at this point begins to be neurotoxic — poison to the brain.

THE STRESS RESPONSE EXPLAINED
Stress was put on the map, so to speak, by a Hungarian — born Canadian endocrinologist named Hans Hugo Bruno Selye (ZEL — yeh) in 1950, when he presented his research on rats at the annual convention of the American Psychological Association. To explain the impact of stress, Selye proposed something he called the General Adaptation Syndrome (GAS), which he said had three components. According to Selye, when an organism experiences some novel or threatening stimulus it responds with an alarm reaction. This is followed by what Selye referred to as the recovery or resistance stage, a period of time during which the brain repairs itself and stores the energy it will need to deal with the next stressful event.

The Little Brain Down Under
The tour continues … Sitting under the occipital and temporal lobes of the brain is the cerebellum. It’s about the size of a child’s fist. Because it looks like a separate brainlike structure attached to the underside of the cortex, the cerebellum is sometimes referred to as the “ little brain. ” It’s connected to the brain stem, which in turn connects the brain to the spinal cord. The cerebellum used to be relegated to the very simple role of helping us maintain balance when we walk or run, but modern neuroscience has found that the cerebellum plays a much larger and more important role than that.

Gray Matters
The term gray matter usually evokes an image of the cortex, because that ’ s the part most visible in pictures of the brain. In fact, gray matter makes up not only the cerebral cortex but also the central portion of the spinal cord and areas called the cerebellar cortex and the hippocampal cortex. This dense tissue is packed full of neuronal cells, their dendrites (branching, root — like endings), axon terminals (the other end), and those sticky glial cells I mentioned earlier. The cortex is the area of the brain where the actual processing of information takes place. Because of its relative size and complexity, it ’ s easy to understand why it plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness.
