Some symptoms of dementia include memory loss, confusion, impaired motor functions, change in personality and inability to reason. Dementia is a term used to refer to a group of conditions that affect the brain, notes WebMD.
Some common types of dementia include Alzheimer's disease, Parkinson's disease, Huntington's disease, vascular dementia, frontotemporal dementia and mixed dementia. These conditions may produce varied signs and symptoms. However, the most common symptom is loss of memory.
Individuals with this condition tend to change in personality. They may start behaving inappropriately and get agitated easily. As dementia progresses, symptoms may become severe and increase. Hallucinations and paranoia are common symptoms that develop. Other signs of dementia include having difficulty in completing complex tasks, disorientation, impaired speech, poor communication skills and impaired coordination.
Diagnosis of dementia is often done by examining the patient's medical history, noting the symptoms and performing a physical examination. If initial diagnosis does not give definitive results, doctors may order certain tests, including psychiatric evaluation, laboratory tests and brain scans.
There is no cure for dementia. However, there are certain treatment options that may help slow down the effects of the condition and help in management of symptoms, notes the National Institutes of Health's MedlinePlus. Medications and therapies are among the options available for management.
