![]() This has to do completely with the fact that with dementia the brain is constantly rewiring itself and thus information becomes lost causing the person who has dementia to become confused as well as disoriented, and in most cases completely unaware of the passage of time. Through studies, dementia is both a cause and an effect of dyschronometria. Dementia ĭementia has a huge effect on dyschronometria and was one of the main sources of how dyschronometria was discovered. It remains unclear as to whether dyslexia is a symptom of dyschronometria, a cause, or both. These children would place little to no importance on their present state, a behavior that would continue into adulthood. ![]() When dyslexia was studied within children, it was found that dyslexic children were often stressed as well as mentally exhausted. Dyslexia Īn interesting case of dyschronometria has to do with dyslexia. Other probable causes for the deterioration of brain matter in the elderly include increased supranational activation, decreased cerebellar activation (which is consistent with fronto-cerebellar dissociation). This also explains why dyschronometria is seen more commonly in the elderly due to the deterioration of physical brain matter with age. These traumas are especially detrimental to children and the elderly due to decreased brain matter, increasing the risk that trauma may damage the cerebellum. Examples of trauma include a car accident, stroke, epilepsy, and head trauma. This can be by form of a trauma, or by disease and genetics. The most common cause of cerebellar ataxia, and by extension dyschronometria, is cerebellar damage. Ĭross-section of human cerebellum, showing the dentate nucleus, as well as the pons and inferior olivary nucleus Causes Dyschronometria does not affect the 24-hour circadian rhythm, which is sustained by a different biological process. This often takes form in forgetting basic time keeping unless a timer is set, such as when cooking for example. This can result from a loss of focus, however, more often than not the individual affected can no longer tell what they are doing and they become disoriented. For example, when asked to wait for thirty seconds, or tap every second that has gone by, those affected will be able to perform the task for a short time and then become derailed. The defining symptoms, while not completely understood, involve time perception. Signs and symptoms Ĭommon signs of dyschronometria are often generic to cerebellar ataxia, including a lack of spatial awareness, poor short term memory, and inability to keep track of time.
