Distinguishing Between Medical and Psychiatric Conditions: Q&A with Barbara Schildkrout, MD

TCPR: You brought up a common symptom: anxiety. We are almost always going to have patients saying that they’re anxious—whether it’s part of their depression or a distinct anxiety disorder. What kind of medical problems can produce symptoms of anxiety?

Dr. Schildkrout: Well, if we focus on “anxiety attacks,” pheochromocytoma is a rare condition that can mimic panic attacks. More commonly, though, episodes of anxiety can be associated with partial seizure disorders. During a seizure, there can be an experience of anxiety and fear that comes out of the blue. This is another instance in which it is crucial to listen carefully to the words the patient is saying. Does the person experience anxiety or fear? Fear is more characteristic of a seizure, but people may report a lot of anxiety before or after an episode. Patients who are having multiple seizures may have a lot of anxiety in between the seizure episodes.

TCPR: So if we have some suspicion of seizure, do we automatically refer a patient to a neurologist? We don’t want to over-refer people for tests such as EEGs because of cost and potential false-positive results, correct?

Dr. Schildkrout: Yes, it’s tricky. It can also be challenging to find neurologists who know a lot of about seizures outside an academic center area. You have to determine your level of certainty about whether your patient really is having seizures. And that is partly based on whether the patient’s symptoms are classical for focal seizures: 1) episodes that are stereotypical for the individual, although a patient may have more than one type of episode; 2) episodes that come on “out of the blue” and that have typical features.

TCPR: What are some of these typical features?

Dr. Schildkrout: The list of possible seizure-related symptoms is huge, but the typical ones are: fear or a sense of dread or impending doom; sensations in the chest or abdomen; frequent déjà vu experiences; alterations in one’s sense of reality, including dissociative episodes; hallucinations of smell, taste, or sound; and possible visual or kinesthetic illusions or hallucinations. And these episodes don’t last very long, usually minutes and are often followed by fatigue (Schomer DL et al, Principles of Behavioral and Cognitive Neurology 2nd ed. Oxford, England: Oxford University Press; 2000:373–405). This presentation is absolutely classical, and anyone experiencing this constellation of symptoms surely needs a workup. If we are talking about less typical symptoms then you have to make a judgment call. One final thing—look at the symptoms in the context of the person’s whole character.

TCPR: Can you be more specific?

Dr. Schildkrout: Yes. Here’s an example. I know of a patient who was in psychotherapy for a psychological condition and who reported brief episodes of hallucinations of the smell of rotten eggs. She suffered from extreme anxiety at times and experienced emotions very intensely, but not in the context of a borderline personality disorder, narcissistic disorder, or bipolar diagnosis. The patient was very mature and related well interpersonally. Her symptoms had been going on for years. Keep in mind that intensification of emotions has been hypothesized to be related to repeated firing of limbic circuitry, as occurs with tempo-limbic seizures. Although the patient responded to lamotrigine, she never had a documented abnormal EEG. She eventually did see an epileptologist. Her screening EEG was negative, and the epileptologist didn’t want to do a more extended evaluation. I believe that the patient’s emotional presentation was throwing the specialist off track; a psychiatric diagnosis seemed most likely to the specialist. The psychiatrist ended up contacting the epileptologist afterwards to advocate that this patient’s case needed to be further pursued. The situation had been very seriously thought through; there were good reasons to believe that this woman had a long-standing seizure disorder, that there was a deep focus, and that that was the reason for the absence of findings on the screening EEG.

TCPR: Was the conversation successful? How was the psychiatrist able to get the doctor to take it seriously?

Dr. Schildkrout: Yes, it was a successful conversation. I think part of the reason was that the psychiatrist really knew the history of the patient’s response to lamotrigine: the olfactory hallucinations, and the fact that although she experienced very intense emotions, the patient was an emotionally healthy person. This gets us back to the point—seeing symptoms in the context of the whole person.

“A patient may come in feeling depressed or overwhelmed because of a recent move or the death of a partner, but in fact this could be the presentation of an early dementia in which the person has lost adaptive flexibility.

TCPR: You bring up an important point that I think we as psychiatrists wrestle with—am I providing a good enough level of care if I’m not in contact with my patient’s primary care physician or other doctors? In a typical day we may have a patient who comes in with a fairly complicated psychiatric presentation who has a primary care doctor, is being treated for diabetes or a cardiac condition, and has a few medications on board. I think it is probably the rare psychiatrist who has time to pick up the phone and call that patient’s primary care doctor.

Dr. Schildkrout: The primary care doctors often don’t have a lot of time either. So it’s a challenge on both ends. Initially, what I do is work through the patient; I emphasize that the issues we are talking about need to be discussed with a primary care doctor or specialist. But there are times when I feel that a certain concern of mine isn’t something that the patient can convey. Sometimes I need to have a personal conversation with the PCP in order to “be on the same page,” or to work out some kind of conflict or misunderstanding. This is when I pick up the phone.

Although you are not a PCP, you may be the one doctor a patient actually sees. Your job is to think beyond the DSM and keep in mind the possibility of a medical disorder. It makes sense to do a mental status exam and a medical review of systems, even if you can only do them quickly.

TCPR: Is there a particular medical condition in which you often find yourself consulting with a patient’s PCP?

Dr. Schildkrout: Yes, dementia, especially if the person is lacking in insight.

TCPR: We know that some of the early symptoms of dementia are changes in personality, changes in the way people respond to others. What are some other symptoms we might miss or might not necessarily associate with this illness that we should be looking for?

Dr. Schildkrout: You just mentioned a couple: a loss of empathy, disinhibition, and apathy, failing executive functions and social withdrawal. Especially in older patients, these can present as depression. Keep in mind that many patients are knowledgeable about Alzheimer’s disease and may willingly report memory complaints. But I think they’re not as tuned into the kinds of behavioral changes that can occur with frontal dementia, such as poor judgment, lack of insight, or obsessional behavior, particularly related to eating, hoarding, etc. (Block NR et al, Am J Geriatr Psychiatry 2015 (15)00188–8.doi:10.1016/j.jagp.2015.04.007 [Epub ahead of print]). Generally, the OCD behavior associated with dementia is somewhat atypical in that the person doesn’t necessarily feel distressed by their symptoms. Dementia patients may also have delusions and hallucinations. With Lewy body dementia, which is actually very common, visual hallucinations are an early symptom. Psychiatrists need to be especially aware of Lewy body disease because if patients with this disease are prescribed an antipsychotic, it can make the dementia precipitously worse. If you have a suspicion of this disease, you should check the patient’s history for atypical reactions to medications like Haldol. Psychotropic medications make these patients much worse, so that kind of history can lend support for a Lewy body dementia diagnosis.

TCPR: That’s important information to know. Any other presentations we should watch out for?

Dr. Schildkrout: What psychiatrists often see is someone with a change of circumstances who is unable to adapt. A patient may come in feeling depressed or overwhelmed because of a recent move or the death of a partner, but in fact this could be the presentation of an early dementia in which the person has lost adaptive flexibility. Many people with early dementias are able to keep up established routines that don’t involve new learning. But these same individuals, faced with something like a move from their familiar neighborhood, will find it problematic to learn the new things that are involved in adapting to the change of circumstances. So that’s another way that dementias may present to psychiatrists. Also, keep in mind that it isn’t just the elderly who can develop dementia; frontal dementias can present in mid-life, and there are people with strong genetic family histories of Alzheimer’s who can present as early as in their 30s.

TCPR: That is very valuable insight. Thank you, Dr. Schildkrout.
