Brains and Atypical Attention
Brains and Atypical Attention
Chapter 4 discusses the feasibility and pitfalls of using brain imaging and recording technologies such as fMRI, PET and SPECT scans, magnetoencephalography, transcranial magnetic stimulation and event-related potentials in neurodevelopmental disorders. While such techniques are useful in assessing the typically developing brain, their full potential is yet to be realized in disorders that result in atypical brain development. Nevertheless, brain imaging and recording techniques can offer some clues to the underlying causes of attention deficits. For example, research in children with ADHD offers promising insights into how the atypical brain processes information in the attention domain. However, issues such as degree of intellectual impairment, anxiety levels, and attention difficulties pose significant problems in obtaining reliable imaging neuropsychological data in some neurodevelopmental disorders. The authors propose that the next decade will see such challenges evaporate as brain imaging and recording technologies become more refined and accessible to a wider range of neurodevelopmental disorders.
