Expert interview: discovering neuropsychology (1/3)

Hello Timothée Albasser, thank you for agreeing to answer our questions. Can you explain to us what neuropsychology is all about?

Neuropsychology is the study of cognitive, emotional and behavioral disturbances caused by brain injuries. This disciplinary field lies at the crossroads of neurology, psychiatry, psychology and neuroscience in general. 

From neurology, neuropsychology makes constant reference to the brain injury or neurophysiological disorganization that is responsible for disorders (Cambier et al., 2000). It borrows concepts form psychology to describe behaviors. Psychiatry provides a reading of psychopathological disorders and the comorbidity factors sometimes associated with them. Neuroscience sheds light on mental activities, for example, through neuroimaging (magnetic resonance imaging (MRI), PET scan).

According to the current position of the Société de neuropsychologie de langue française (the French-Speaking Neuropsychological Society), neuropsychology deals with the relationships between the mental processes underlying brain activity, cognitive functions, and emotional behavior, because brain damage affects both the patient's cognitive efficiency, emotional functioning and behavior. 

The expertise of clinical psychologists specializing in neuropsychology must be founded in knowledge of the neural bases of behavior, cognitive theories, theories of the development of the human psyche, its organization and its normal and pathological manifestations. It also requires training in listening to the patient and his family, in a comprehensive approach to the situation.

When do patients come to see you? Can they make an appointment directly?

We are called to see any type of patient reporting a memory or cognitive problem in general. The purpose of the neuropsychological assessment is then to objectify (or not) this problem and to bring to light the presence of possible cognitive disorders. So, any person who has a cognitive problem can talk about it with their primary care doctor, who will send a request directly to our department. Usually, the patient is called in within a month. 

Also, as I work in a university hospital, I am in direct contact with the neurology, geriatrics, neurovascular and rheumatology departments.  Thus, I regularly see patients hospitalized in these departments, in order to conduct cognitive assessments

Why a neuropsychologist and not a neurologist straight away?

We work closely with neurologists. The neuropsychologist is often on the front line and is the one who sees the patient in the first stage, at the request of the primary care doctor. Thus, the neuropsychologist will collect the concerns of the patient and his or her family and friends, and will look for elements explaining how the disorder developed, how it evolves and its repercussions on the patient's daily life. The neuropsychological assessment will therefore serve to objectify (or not) the presence of cognitive disorders and will allow diagnostic hypotheses to be made. Following this assessment, the neuropsychologist will be able to propose a list complementary tests if necessary (MRI, blood biology, sleep tests, etc.), in order to determine the etiology of the disorders.

It's only after all these tests that the patient sees a neurologist. During this consultation, a neurological assessment is also carried out. At the end, the neurologist will have all the information needed to make a diagnosis about the origin of the patient's cognitive problems. In the case of Alzheimer's disease, the test most likely to diagnose the disease is the study of biomarkers (levels of beta-amyloid and tau) in the cerebrospinal fluid (through a lumbar puncture).

What is a neuropsychological assessment exactly?

Neuropsychological assessment can take several forms. A "standard" neuropsychological assessment lasts an average of an hour and a half. Neuropsychological tests consist of, for the most part, "paper-and-pencil" type tasks. Some tasks are also carried out on a computer, particularly with regard to the evaluation of attention and focus. These tests are standardized - the testing period is the same for all patients, and the results are interpreted by comparing them with the norms obtained in patients matched in terms of age, sex and socio-cultural level.

How is the assessment conducted?

Each assessment begins with a preliminary clinical interview to establish a relationship of trust, during which the neuropsychologist:

  1. Explains the objectives and content of the assessment.

  2. Asks the patient what he or she expects from the assessment and tries to clear up any misunderstandings about its purpose and the psychologist's role.

  3. Inquires about school and/or work history, personal and family life events, everyday activities, medication, and alcohol and drug use.

  4. Has the patient clarify the history of the problems. Even if the information is available in the medical record or in school reports, it is still essential to take into account the patient's subjective point of view and the way in which he or she shows and describes his or her own difficulties.

  5. Assesses emotional state, looking for anxiety and depressive symptoms. The neuropsychologist also looks for factors that could affect mental performance during the examination. For example, a recent life event with a strong emotional impact such as job loss, bereavement, or more trivial things which may interfere with alertness, such as insomnia or fasting. In the latter case, subjects must eat before the assessment.

  6. Notes the handedness (being right-handed, left-handed or ambidextrous) and the socio-cultural level of the patient. The socio-cultural level allows the neuropsychologist to compare the results with the norm, depending on age and level of education. The standards for psychometric tests are included in each test manual. The comparison between the patient’s results and those of his or her age and education level allows the neuropsychologist to examine their significance. However, the use of these tests alone does not allow him or her to make a definitive diagnosis.

  7. Reiterates the ethical rules of test data confidentiality and respect of patient rights with which the neuropsychologist must comply. In addition, psychologists who have never completed an internship or received theoretical training in neuropsychology are not qualified to conduct a neuropsychological assessment. Additionally, in the case where the neuropsychologist operates in private practice, it is during this preliminary interview that the financial terms (cost of the assessment, coverage or non-coverage by insurance, Medicare, or Medicaid) must be clearly defined with the patient.

  8. Before concluding the interview, the neuropsychologist should ask the patient if he or she has any other questions, for example, about the assessment or any other topic that he or she feels is important and has not been discussed. It should be noted that the specialist will not be able to indicate to them during the assessment whether their answers to the various tests are right or wrong. Usually, the patient is given a summary report of the assessment results.

Why is it important to talk not only with patients but also with loved ones?

Apart from the patient, the person who suffers most is the so-called "primary caregiver". This is usually the patient's spouse, but it can also be children, other family members or even friends. Thus, we are present first and foremost to listen to the caregiver's concerns, to gather their feelings about their loved ones' cognitive problems and to alleviate their suffering.

The primary caregiver’s input allows us to gather crucial information and will give us an idea of how the patient functions at home, his or her self-sufficiency, what he or she is capable of doing and, finally, the observed difficulties. This perspective will complement the patient's own and will give us the keys to select the best neuropsychological tests to perform.  

What happens after the neuropsychological assessment?

After the neuropsychological assessment, it is important to take the time to ask the patient how he or she feels about the tasks they've just completed: did he or she find them difficult? Challenging? Conversely, did he or she find them easy? This is also the time during which we present the results to the patient and, if the patient wishes, to his or her family and friends. If the neuropsychological assessment is normal, it will then have a reassuring effect on the patient. In this case, we usually do not offer a follow-up. If abnormalities are found, we generally offer a follow-up with a neurologist or a geriatrician from our department, who will then try to clarify the etiology of the disorders, possibly also by carrying out additional tests.
