CJD often begins with personality changes such as anxiety, depression, memory loss and confusion. As the disease progresses, mental symptoms become more severe. Ultimately, people with CJD develop dementia - a disorder that robs them of the ability to speak, think, reason, remember, and move. Although the symptoms of CJD sometimes resemble those of other neurological disorders such as Alzheimer's and Huntington's disease, CJD tends to cause a much faster decline than other types of dementia.
