Diagnostic Criteria for Parkinson’s DiseaseThe American Psychiatric Association (APA) Diagnostic and Statistical Manual of Mental Disorders (2014) categorizes neurocognitive disorders (NCD) as those that have a primarily cognitive deficit and are acquired, not developmental. For this assignment, I will be looking into major or mild NCD due to Parkinson’s Disease (PD).The key factor in diagnosing NCD due to PD is that the individual must first have a formal diagnosis of PD with behavioral disturbance. PD may cause feelings of distraction and disorganization along with cognitive impairment. There are three different categories in the DSM-5 diagnosis: NCD possibly due to PD, NCD probably due to PD, and NCD due to PD (APA, 2014). Per the diagnostic criteria, the cognitive deficit must have an insidious onset with agradual progression, the NCD must not be able to be attributed to another medical or mental disorder. The sub-criteria include that there not be evidence of mixed etiology such as another neurodegenerative or cerebrovascular disease, another neurologic or mental or systemic disease that may be the cause and that the NCD can clearly be identified as occurring after the PD (APA,2014). If one of these sub-criteria are met, then it is categorized in the “possibly due to” and if both are met, then it becomes that the NCD is probably due to PD (APA, 2014). PD is a movement disorder which can be diagnosed using the Movement Disorder Society (MDS)
