A diagnosis of dementia may be delayed or missed because early symptoms develop gradually and are often associated with the normal aging process. In addition, symptoms of dementia can mimic symptoms of a variety of diseases, disorders or conditions, such as depression, TIA, stroke, psychosis, and delirium, which can all accompany dementia or can be distinct and separate diagnoses not related to dementia.
In addition, a misdiagnosis of the underlying cause of dementia is possible because there are many possible causes, some of which can be difficult to diagnose. These include vascular dementia, Alzheimer's disease, Creutzfeldt-Jacob disease, bovine spongiform encephalopathy, frontotemporal dementia, thyroid diseases, brain tumor, and vitamin B deficiency. Other causes include AIDS, syphilis, alcoholism, hydrocephalus, depression, and chronic subdural hematoma.
Undiagnosed stroke leads to misdiagnosed aphasia: BBC News UK reported on a man who had been institutionalized and treated for mental illness because he suffered from sudden inability to speak. This was initially misdiagnosed as a "nervous breakdown" and other mental conditions. He was later diagnosed as having had a stroke, and suffering from aphasia (inability to speak), a well-known complication of stroke (or other brain conditions).
Alzheimer's disease over-diagnosed: The well-known disease of Alzheimer's disease is often over-diagnosed. Patients tend to assume that any memory loss or forgetulness symptom might be Alzheimer's, whereas there are many other less severe possibilities. Some level of memory decline is normal with aging, and even a slight loss of acuity may be noticed in the 30's and 40's. Other conditions can also lead a person to show greater forgetfulness. For example, depression and depressive disorders can cause a person to have reduced concentration and thereby poorer memory retention.
Dementia may be a drug interaction: A common scenario in aged care is for a patient to show mental decline to dementia. Whereas this can, of course, occur due to various medical conditions, such as a stroke or Alzheimer's disease, it can also occur from a side effect or interaction between multiple drugs that the elderly patient may be taking. There are also various other possible causes of dementia.
Tremor need not be Parkinson's disease: There is the tendency to believe that any tremor symptom, or shakiness, means Parkinson's disease. The reality is that there are various possibilities, such as benign essential tremor, which is mostly harmless. see the various causes of tremor and misdiagnosis of Parkinson's disease.
ADHD under-diagnosed in adults: Although the over-diagnoses of ADHD in children is a well-known controversy, the reverse side related to adults. Some adults can remain undiagnosed, and indeed the condition has usually been overlooked throughout childhood. There are as many as 8 million adults with ADHD in the USA (about 1 in 25 adults in the USA). See misdiagnosis of ADHD or symptoms of ADHD.
Rare diseases misdiagnosed as Parkinson's disease: A rare genetic disorder is often misdiagnosed as Parkinson's disease for men in their 50's. The disease Fragile X disorder can show only mild symptoms in the early years, and Parkinsons-like symptoms around age 50. See misdiagnosis of Parkinson's disease.
Bipolar disorder misdiagosed as various conditions by primary physicians: Bipolar disorder (manic-depressive disorder) often fails to be diagnosed correctly by primary care physicians. Many patients with bipolar seek help from their physician, rather than a psychiatrist or psychologist. See misdiagnosis of bipolar disorder.
Eating disorders under-diagnosed in men: The typical patient with an eating disorder is female. The result is that men with eating disorders often fail to be diagnosed or have a delayed diagnosis. See misdiagnosis of eating disorders or symptoms of eating disorders.
Depression undiagnosed in teenagers: Serious bouts of depression can be undiagnosed in teenagers. The "normal" moodiness of teenagers can cause severe medical depression to be overlooked. See misdiagnosis of depression or symptoms of depression.
Brain pressure condition often misdiagnosed as dementia: A condition that results from an excessive pressure of CSF within the brain is often misdiagnosed. It may be misdiagnosed as Parkinson's disease or dementia (such as Alzheimer's disease). The condition is called "Normal Pressure Hydrocephalus" (NPH) and is caused by having too much CSF, i.e. too much "fluid on the brain". One study suggested that 1 in 20 diagnoses of dementia or Parkinson's disease were actually NPH. See misdiagnosis of Alzheimer's disease or misdiagnosis of Parkinson's disease.
Undiagnosed anxiety disorders related to depression: Patients with depression (see symptoms of depression) may also have undiagnosed anxiety disorders (see symptoms of anxiety disorders). Failure to diagnose these anxiety disorders may worsen the depression. See misdiagnosis of depression or misdiagnosis of anxiety disorders.
