Is an underlying condition causing your fuzzy thinking?

The top five causes you may be overlooking.

You know the feeling: you can't find a particular word, remember someone's name, or concentrate the way you once did. Is it just aging, or is something else to blame? "It's easy to underestimate how underlying conditions affect memory and thinking, and they are often overlooked," says Dr. Shreya Raj, a neuropsychiatrist with the Center for Brain/Mind Medicine at Harvard-affiliated Brigham and Women's Hospital.

Common causes

What you should do

When trouble with concentration or memory interferes with your day, it's probably time to talk to your primary care doctor. Report any additional symptoms you may be having, such as fatigue, muscle weakness, sadness, daytime sleepiness, or anxiety. You might need some blood tests to check your thyroid hormones or B12 levels (neither test is ordered routinely), or a sleep test if you have sleep apnea symptoms.

Often, treating an underlying condition can restore your clarity of thinking. "When we treat depression or sleep apnea, for example, we see a sudden improvement in memory and focus," says Dr. Raj. "And if a medication side effect is the problem, changing the dose or type of drug may resolve the problem."

If treating an underlying condition doesn't sharpen thinking skills, your doctor may refer you to a neuropsychologist for formal tests of your thinking ability, particularly signs of dementia. Most of the time, however, people with fuzzy thinking do not have dementia.

Fuzz busters

When you're struggling with fuzzy thinking, lifestyle changes like these can bring more clarity.

Get more sleep. Aim for seven to eight hours of sleep per night. "Older adults to tend to sleep less, but if you're getting too little sleep, you won't think as sharply as you could," says Dr. Shreya Raj. Boost your Z's by going to sleep and waking at the same time each day, and avoiding caffeine, particularly after noon.

Exercise more. Try to get 150 minutes of moderate-intensity activity per week, such as brisk walking. You'll get more sleep and boost blood flow to the brain. Many studies have shown that aerobic exercise in particular improves thinking skills.

Change your diet. "Not eating healthfully makes you more sluggish, even in thinking. Studies have shown the Mediterranean diet may improve cognitive function," says Dr. Raj. The diet includes fresh vegetables and fruits; whole grains; olive oil; nuts; legumes; fish; moderate amounts of poultry, eggs, and dairy; moderate amounts of red wine; and red meat only sparingly.

What a therapist can do for you

Many men resist talking about their problems, but there are times when it's necessary.

Men often like to think of themselves as the strong, problem-solver type who never needs help, especially when it comes to their emotional and mental issues. But men should never bottle up their feelings and tough it out, according to Dr. Darshan Mehta, medical director of the Benson-Henry Institute for Mind Body Medicine at Harvard-affiliated Massachusetts General Hospital.

"Your mental health is equally as important as your physical health and proper nutrition. Not addressing negative feelings can carry over to all aspects of your life and have a profound impact," he says.

Loneliness has same risk as smoking for heart disease

Loneliness and social isolation raises your risk of heart attack, stroke, and even early death, says a new study. The risk was similar to light smoking or obesity. 

How to stay motivated

Want to make a change but wondering how to stay motivated? Dr. Srini Pillay talks about the things that can impact personal motivation and the power of a sense of meaning to help you stick with your goals.

What men can gain from therapy

Men are often reluctant to seek therapy. After all, it involves asking for help and talking candidly about one’s emotions, two things that many men are eager to avoid. But men should know that there’s no need to “tough out” whatever they’re going through. There are plenty of professionals out there who are ready and willing to lend an ear.

Lend a hand, help your heart?

People who do volunteer work may reap benefits beyond the satisfaction of helping others.

If you volunteer on a regular basis, perhaps you've experienced the emotional rewards of donating your time. What you might not realize, however, is that volunteering may offer some added advantages for your heart.

More than sad: Depression affects your ability to think

We often think of depression as making someone feel “down,” but it can sometimes show up as cognitive symptoms â€� for example, trouble with adapting to new information or thinking through a solution to a problem. Researchers recently determined that several common depression medications are not effective at relieving cognitive symptoms. But there are several things people with depression can try to help return themselves to their usual level of cognitive functioning.
