“Confusing Medical Ailments With Mental Illness”

The Wall Street Journal Health Journal , August 9, 2011

An elderly woman’s sudden depression turns out to be a side effect of her high blood-pressure medication.

A new mother’s exhaustion and disinterest in her baby seem like postpartum depression—but actually signal a postpartum thyroid imbalance that medication can correct.

A middle-aged manager has angry outbursts at work and frequently feels “ready to explode.” A brain scan reveals temporal-lobe seizures, a type of epilepsy that can be treated with surgery or medication.

More than 100 medical disorders can masquerade as psychological conditions, according to Harvard psychiatrist Barbara Schildkrout, who cited these examples among others in “Unmasking Psychological Symptoms,” a book aimed at helping therapists broaden their diagnostic skills.

Different Diagnoses

More than 100 medical disorders can masquerade as psychological conditions or contribute to them, complicating treatment decisions.

WHAT
SEEMS LIKE …
MAY ACTUALLY BE …
Depression Underactive thyroid; low vitamin D or B-12 or folate; diabetes; hormonal changes; heart disease; Lyme disease; lupus; head trauma, sleep disorders; some cancers and cancer drugs
Anxiety Overactive thyroid; respiratory problems; very low blood pressure; concussion; anaphylactic shock
Irritability Brain injury; temporal lobe epilepsy; Alzheimer’s disease and early stage dementia; parasitic infection; hormonal changes
Hallucinations Epilepsy; brain tumor; fever; narcolepsy; substance abuse
Cognitive changes Brain injury or infection; Alzheimer’s; Parkinson’s; liver failure; mercury or lead poisoning
Psychosis Venereal disease; brain tumors and cysts; stroke; epilepsy; steroids; substance abuse

Studies have suggested that medical conditions may cause mental-health issues in as many as 25% of psychiatric patients and contribute to them in more than 75%.

Untangling cause and effect can challenge even seasoned clinicians, and the potential for missed diagnoses is growing these days, said Dr. Schildkrout, who has more than 25 years of clinical practice in the Boston area. Most mental-health counselors rely on primary-care doctors to spot medical issues, but those physicians are increasingly time-pressed and may not know their patients well. Neither do the psychiatrists who mainly write prescriptions and see patients only briefly, she said in an interview.

Common culprits include under- or over-active thyroid glands, which can cause depression and anxiety, respectively. Deficiencies of vitamins D, B-12 and folate, as well as hormonal changes and sleep disorders have also been linked to depression.

Diabetes, lupus and Lyme disease can have a variety of psychiatric symptoms, as can mercury and lead poisoning and sexually transmitted diseases. Many medications also list mood changes among their side effects, and substance abuse is notorious for causing psychiatric problems.

Some underlying conditions are readily treatable. Others, such as Alzheimer’s and Parkinson’s disease and some brain tumors, are not. But a correct diagnosis can save months or years of frustration and ineffective treatment.

In some cases, a psychological problem is just the first sign of a serious medical issue. “Depression predicts heart disease and heart disease predicts depression,” said Gary Kennedy, director of the geriatric psychiatry at Montefiore Medical Center in Bronx, N.Y.

About one-third of people who have their first episode of depression after age 55 have changes in brain circuits that are associated with hypertension, diabetes and heart attacks. Such patients are usually apathetic, have difficulty with executive planning and don’t respond well to antidepressants. Making sure their blood pressure and blood-sugar levels are on target is crucial, though medical and psychotherapy may be needed as well, Dr. Kennedy said.

Recognizing an underlying medical condition can be particularly difficult when there is also a psychological explanation for a patient’s dark moods. For example, victims of domestic violence are often anxious, depressed and withdrawn—but mild brain injury could be causing such symptoms, too.

Warning Signs

When to suspect a mental problem may be medical:

• Sudden change in mood or personality

• History of head trauma

• Depression that occurs for the first time after age 55

• Recent travel or exposure to infections

• Any rash, swelling, drooping eyelid; facial tic

• Standard medication or therapy isn’t effective

Similarly, a former college athlete who becomes angry and irritable in his 40s could be suffering a midlife crisis—or delayed reaction to head injuries sustained decades earlier. “We now know that multiple concussions can have a sleeper effect for years. Then one day, out of the blue, you start acting explosive and depressed,” due to a brain swelling known as chronic trauma encephalopathy, said Jerrold Pollak, a neuropsychologist at Seacoast Mental Health Center in Portsmouth, N.H., and lead author of an article on distinguishing mental from medical disorders in the Journal of Clinical Psychology Practice this spring.

If the head-injury diagnosis is missed, Dr. Pollak added, the patient could be in psychotherapy for months, “thinking that he has trouble with his father or feels like a failure for not becoming a pro athlete.”

Giving every patient who seeks psychological help a brain scan first would be prohibitively expensive and likely yield many confusing results. But experts say mental-health counselors should ask patients about their medical histories as well as emotional issues, and make sure they’ve had a recent physical exam.

Tell-tale signs of underlying medical problems include significant changes in energy, weight, appetite or sleep, which could be due to an endocrine disorder. Sudden changes in mood or personality, visual hallucinations and alternations in smell, taste or tactile senses could signal a brain tumor or other abnormality.

Sometimes a single physical sign can broaden a clinician’s diagnostic thinking. Manhattan psychiatrist Drew Ramsey recalled that early in his career, he examined a patient with daily panic attacks and noticed a swelling on her shins, a classic sign of Graves’ disease, a form of overactive thyroid that can cause severe anxiety.

Like other psychiatrists, Dr. Ramsey said he always takes a medical history and orders blood tests for patients. He found that one was anemic and improved markedly when meat was added to her diet. Another who was depressed and drinking heavily was low on vitamins D and B-12.

Similarly, Dr. Schildkrout once treated a 50-year-old woman for mood swings and noticed a slight slurring to her speech. While it could have been dismissed as ill-fitting dentures, it turned out to be the first sign of amyotrophic lateral sclerosis, which also causes severe fatigue and odd jags of laughing and crying in its early stages.

Some patients may benefit from both psychological counseling and medical help. Therapists need not turn patients away while medical issues are being explored, experts say. “Clinicians can say, ‘While we work on these issues, let’s also discuss any possible medical conditions that could be contributing, so we can at least rule them out,”‘ Dr. Pollak said.

Finally clarifying a diagnosis can be a relief to clinicians and patients—particularly when therapy hasn’t been working or patients have spent years blaming themselves. “When you find the right diagnosis, not only is there appropriate treatment, but it can make a dramatic improvement in terms of healing their self esteem,” Dr. Schildkrout said.

I am a tenth generation American, descended from a family that has been working a farm that was deeded to us by William Penn. The country has changed around us but we have held true. I stand in my grandmother’s kitchen, look down the valley to her brother’s farm and see my great-great-great-great-great-grandmother Hannah standing on the porch. She is holding the baby, surrounded by four other children, and saying goodbye to her husband and oldest son who are going off to fight in the Revolutionary War. The war is twenty miles away and her husband will die fighting. We are not the Daughters of the American Revolution; we were its mothers. My father, Milton C. Woodlen, got his doctorate from Temple University in the 1940’s when—in his words—“a doctorate still meant something.” He became an education professor at West Chester State Teachers College, where my mother, Elizabeth Hope Copeland, had graduated. My mother raised four girls and one boy, of which I am the middle child. My parents are deceased and my siblings are estranged. My fiancé, Robert H. Dobrow, was a fighter pilot in the Marine Corps. In 1974, his plane crashed, his parachute did not open, and we buried him in a cemetery on Long Island. I could say a great deal about him, or nothing; there is no middle ground. I have loved other men; Bob was my soul mate. The single greatest determinate of who I am and what my life has been is that I inherited my father’s gene for bipolar disorder, type II. Associated with all bipolar disorders is executive dysfunction, a learning disability that interferes with the ability to sort and organize. Despite an I.Q. of 139, I failed twelve subjects and got expelled from high school and prep school. I attended Syracuse University and Onondaga Community College and got an associate’s degree after twenty-five years. I am nothing if not tenacious. Gifted with intelligence, constrained by disability, and compromised by depression, my employment was limited to entry level jobs. Being female in the 1960’s meant that I did office work—billing at the university library, calling out telegrams at Western Union, and filing papers at a law firm. During one decade, I worked at about a hundred different places as a temporary secretary. I worked for hospitals, banks, manufacturers and others, including the county government. I quit the District Attorney’s Office to manage a gas station; it was more honest work. After Bob’s death, I started taking antidepressants. Following doctor’s orders, I took them every day for twenty-six years. During that time, I attempted%2

    Diabetes Type I remains a massive problem in the North American public health system as well as the whole world. Thank you for the useful article about the illness. Each and every writer should write informative articles like you do so that other people can be benefited. Great post and continue with the awesome writing.

      You are wrong. Diabetes, type I, is not such a problem. It is also known as juvenile on-set diabetes, and is an autoimmune disease in which the pancreas stops producing insulin. If not properly and promptly treated, it can be fatal in a matter of days. Diabetes, type II, accounts for 90-95% of all cases of diabetes, with more than 25 million cases in the United States. In type II diabetes, the pancreas is still producing insulin but the cells have become resistant to it because the cells are clogged with fat (lipids). Because the cells resist the insulin that is trying to get glucose into the cells for energy, the glucose builds up in the blood stream, hence high blood glucose levels.
