Visual Concentration Attention Technology (VCAT) is consisted of visual concentration and attention techniques, a form of neurocognitive therapy. VCAT program is based on the concept of selective and divided attention theories including attentional stimulations to the brain within the visual field that influence the firing rate of neurons, discharge of neurotransmitters, brain waves, and increasing the oxygenated blood flow throughout the brain for an optimal plasticity. 
The human brain is able to continually adapt and rewire itself. Even in old age, it can grow new neurons. VCAT key principles include influencing brain’s neural network functioning and their related neurotransmitters as well as neurogenesis. Neurogenesis is the creation of new neurons. The more active a particular brain cell is, the more connections it develops with its neighboring neurons through a process called dendritic sprouting. A single neuron can have up to thirty thousand such connections, creating a dense web of interconnected activity throughout the brain. Each neuron can then be stimulated directly through experience (real or imagined) or indirectly through these connections from its neighbors, which saves the cell from cell death. Exercising VCAT on regular bases boosts the brain’s rate of neurogenesis throughout life. It increases the rate at which those new brain cells survive and make functional connections into existing neural networks. VCAT’s visual stimulations and its treatment plans are formulated, planed, and developed precisely to do so accordingly to that specific disorder as well as balancing neurotransmitters discharge by enhancing and regulating the neural network firing rates. According to the quantitative pre and post treatment research study conducted by Dr. Nader Siahdohoni on attention, concentration, and memory in individuals with ADHD as well as hundreds pilot studies, empirical and evidence-based-studies, programs such as VCAT could be an effective way in promoting efficient communication among the many nerve cells (neurons) and functional centers located throughout the brain and sensory motor system leading to improvement of attention, concentration, perception, cognition, and memory.
