Dyspraxia is characterized by difficulties with movement, coordination, judgment, processing, memory, and several other cognitive processes. Dyspraxia also has an impact on the immunological and neural systems of the body. There are two types of dyspraxia: motor and intellectual/developmental. People with motor dyspraxia have problems executing movements accurately or smoothly. They may also have problems maintaining posture or holding things. These problems can affect activities such as eating, dressing, writing letters, or using utensils properly. Motor dyspraxia can be caused by brain lesions, especially in areas responsible for planning and executing movements; however, it can also be due to disorders such as autism, cerebral palsy, or stroke. People with intellectual/developmental dyspraxia make up about 10% of those with dyspraxia. They often have trouble organizing and completing tasks, remembering instructions, following directions, managing money, and dealing with change. Like those with motor dyspraxia, individuals with intellectual/developmental dyspraxia can have issues using their hands correctly. Sometimes this problem is due to a developmental disability such as autism or ADHD, but it can also be because these people lack the experience to use their muscles correctly. In either case, someone with intellectual/developmental dyspraxia will need help from others to complete daily tasks.
