If you"ve been concerned about a loved one"s mental cognition, a recent article by Dr Oz provides a list of possible causes that should be ruled out before jumping to the worst case scenario
Worried that a loved one"s forgetfulness, confusion and fuzzy thinking may herald the onset of Alzheimer"s disease? You owe it to him or her and yourself to get a quick check for brain-draining health conditions and other causes that seem like Alzheimer"s but with one BIG difference: Many of these mind-altering problems are treatable and even reversible.
A recent report looked at nearly 1,000 people with dementia and found that up to 30 percent didn"t have Alzheimer"s disease; many had what are treatable medical conditions or negative reactions to medication. Those include:
Vitamin deficiencies: Extremely low levels of folic acid, niacin or vitamins B-1, B-6 or B-12 can cause Alzheimer"s-like symptoms. Blood tests can determine deficiencies. The elderly are at particular risk for low levels of B-6 and B-12, and may need regular "booster" shots to maintain healthy levels. (If you give extra B-12 to someone who has both memory loss and normal levels of B-12, you can reduce memory problems.)
Normal pressure hydrocephalus (NPH): Caused by a buildup of cerebrospinal fluid in the brain, NPH symptoms include difficulty walking, incontinence and trouble concentrating and making decisions. Draining the fluid via a shunt can relieve pressure on the brain and, frequently, return a person to his or her former self.
Depression: Insist on a depression evaluation before your doctor makes an Alzheimer"s diagnosis. Thinking and recall can improve with treatment for depression, though not for those with depression plus Alzheimer"s.
Urinary tract infections: A chronic or frequent bladder infection may trigger delirium in the elderly. Treat the infection, and the mental symptoms go away.
An underactive thyroid: A metabolic slowdown due to an underachieving thyroid gland can leave you fatigued, weak, depressed and forgetful (20 percent of women and 5 percent of men over 60 suffer from this). Blood tests of thyroid hormone levels can reveal the true cause: hypothyroidism, not Alzheimer"s.
Reaction to anticholinergic drugs: Some medications used to treat depression, anxiety, acid reflux, Parkinson"s disease, allergies and overactive bladder may trigger dementia-like side effects. These drugs block acetylcholine, a brain chemical that helps send signals between neurons. Alzheimer"s patients also have depressed levels, which contributes to their confusion and memory loss. (That"s why some medications that slow the progression of Alzheimer"s work by boosting acetylcholine.)
Reaction to digoxin: A medication used to slow your heart rate if you have atrial fibrillation or heart failure, digoxin has been known to reduce brain function; this may trigger dementia-like symptoms.
