MIXED DEMENTIA
Dementia is memory loss and deterioration of mental functions. Dementia occurs after physical changes in the brain and it progress through time. There are many different types of dementia. The most rare but the most serious one is mixed dementia. When more than one dementia is seen concurrently in the brain it is called mixed dementia. In the most common shape of blended dementia, the unusual protein stores related with Alzheimer's infection coexist with blood vessel issues connected to vascular dementia. In a few cases, a individual may have brain changes connected to Alzheimer’s disease, vascular dementia and dementia with Lewy bodies. People with mixed dementia can also show the features of Alzheimer’s disease and Vascular dementia. This can lead to alterations in the brain due to damaged tissue formation and blocked blood vessels.

Prevelance
It is difficult to determine the prevalence of mixed dementia. Researchers have said that people who have been diagnosed with dementia may have other types of dementia. In the autopsy results that were examined after death, the symptoms of Alzheimer's disease, vascular dementia and Lewy bodies were seen. According to the Alzheimer’s Association, it has been seen that the mixed dementia increases and progresses with age.

Symptoms
Mixed dementia shows almost the same characteristics as Alzheimer's disease. It is difficult to clearly define the mixed dementia because it cannot be separated from the Alzheimer's disease and other dementia types. The indication of mixed dementia varies depending on the current dementia conditions. Research suggests that mixed dementia is clinically important and research is still unclear as to how mixed dementia treatment and symptoms differ from regular dementia because the combination of the two dementia conditions can accelerate the progression of dementia or have a composition. People with mixed dementia can see a combination of Alzheimer's disease, vascular disease, and Lewy body symptoms. It is difficult to obtain a clinical finding of mixed dementia, so at this point scientists can not measure brain changes related to dementia in living individuals.

Diagnosis
In terms of ICD-10, mixed dementia is diagnosed when individuals fulfill the criteria for both vascular dementia and Alzheimer's disease. ADDTC(Alzheimer’s Disease Diagnostic Treatment Center ) describes mixed dementia that presents findings of vascular disease together with indications of one or more systemic or brain pathologies believed to be associated with dementia. In the majority of mixed dementia patients, dementia is detected after autopsy has been performed. While diagnosing mixed dementia, your doctor must first collect an in-depth knowledge of your personal medical history, including the relevant familial history. This medical story interview also includes information on how to monitor your specific memory loss symptoms.

Causes and Risks
When mixed dementia is compared with other dementia conditions little is known about specific causes and risk factors. In addition to this, it can be thought that the presence of mixed dementia in elderly individuals contributes to the development of aged mixed dementia. Alzheimer's disease, vascular dementia and Lewy body dementia affect the incidence of mixed dementia. Possible risk factors for Alzheimer's disease, vascular dementia and Lewy body dementia affect the incidence of mixed dementia. Since mixed dementia is usually associated with vascular dementia, vascular risk factors may be important in the development of mixed dementia. For instance, hypertension and high blood pressure can enhance the risk of progressing mixed dementia. Despite being rarely diagnosed with mixed dementia, many researchers believe that mixed dementia deserves more attention because the combination of two or more brain changes related to dementia may have more effect on a single individual in the brain. Evidence suggests that changes in more than one dementia may increase the likelihood of a person developing symptoms. Many researchers believe that an increased understanding of mixed dementia will create a favorable circumstances to decrease the number of people who develop dementia with the recognition that vascular changes are the most common brain changes.

Treatment
Several studies have been conducted on the prevention and treatment of mixed dementia. Some authors suggest that VaD is able to be averted of dementia and that ruling cerebrovascular risk factors such as hypertension will reduce the incidence of VaD. Certainly, hypertension treatment has been shown to greatly reduce the incidence of stroke in elderly individuals. Although a study confirms that isolated systolic hypertension is persuasive in preventing AD and VaD formation,unfortunately less information is known about the stop of dementia itself. Initial results of a multicentre study with galantamine, another anticholinesterase inhibitor, in patients with vascular dementia or mixed dementia showed a advantageous effect on cognitive and non-cognitive outcomes. Treatment studies for mixed dementia have been described as equivalent to 4 to 6 month cognitive regression delays. It is accurate to say that mixed dementia cannot be cured, but possible treatment studies are continuing to solve this difficulty. However, there are alternative treatments and effective medications that can be used to treat mixed dementia symptoms. One of the most important areas of dementia research is risk reduction because mixed dementia can not be cured. Last researches suggests that diet, alcohol abuse, lack of exercise, cardiovascular disease, cholesterol levels, incidence of mild cognitive impairment, diabetes and smoking provide to the development of dementia. A positive lifestyle change, especially in the middle age, is an important step in preventing dementia.
