Psychiatric disorders may be associated with changes in mood, thinking, behavior, sleep, concentration, and perception. The majority of psychiatric diagnoses are based on clinical assessment, history, and symptom discussion. Nevertheless, a psychiatrist may consider neurologic testing in certain cases.
EEG means measuring electrical activity in the brain with the help of electrodes placed on the scalp. EEG allows the doctor to investigate the brain’s electrical activity, especially in cases of suspected seizures and epilepsy. However, it is not performed in all cases of psychiatric disorders.
Understanding the role of EEG will allow understanding why the psychiatrist recommends neurologic examination in some difficult cases.
What Is EEG, and How Does It Relate to Psychiatric Disorders?
The EEG is an examination that records the electrical activity of the brain.
The EEG is a simple and non-invasive procedure.
In psychiatry, it may be considered in cases when symptoms can be attributed to a neurological disorder or in cases of atypical presentations.
EEG should therefore be used by psychiatrists in cases of:
- Suspected seizure activity
- Altered states of consciousness
- Unexplained episodes or unusual movements
- Sudden changes in awareness
- Symptoms suggesting a neurological disorder or
- In order to distinguish between psychiatric conditions and other neurological problems
Nonetheless, it is essential to keep in mind that EEG results are not enough for diagnosing psychiatric disorders on their own. It is necessary to interpret the results in conjunction with the patient’s history and clinical examination.
When Should a Psychiatrist Recommend EEG?
The decision to recommend EEG depends on the individual’s symptoms and medical history. EEG is generally more useful when there is a specific clinical question.
1. Episodes of Altered Awareness
Certain individuals may face temporary instances of confusion and lack of awareness. EEG can be suggested if these instances raise suspicions regarding the prospect of seizures.
This is particularly relevant in cases when psychiatric symptomatology is present yet the phenomenological structure of episodes implies possible neurological involvement.
2. Recurring Crises of Unclear Etiology
The classification of periodic uncommon episodes can be problematic at times based upon the symptoms alone. In the cases when the psychiatrist thinks that the episodes might have certain neurological underpinnings, EEG can be conducted during the assessment.
3. Suspected Seizure Activity
EEG is significantly used in the diagnosis of suspected seizures and epilepsy. A patient treated for mental disorders who has sudden seizure-like episodes may be referred for neurological evaluation.
4. Complex Neuropsychiatric Presentation
In certain cases, patients can have manifestations of both neurological and psychiatric symptoms. In this case, close collaboration between psychiatry and neurology can help establish whether further investigations such as EEG are needed.
5. Abrupt Behavioral Change
Drastic changes in behavior or mental status can be caused by a variety of factors. In selected cases, especially if the onset is sudden or if there are changes in consciousness or other neurological signs, the diagnosis warrants further medical investigation.
EEG Does Not Diagnose Every Psychiatric Disorder
It’s necessary to know that psychiatric disorders such as depression, generalized anxiety disorder, and various mental illnesses are usually diagnosed from a clinical perspective.
EEG cannot be considered as a universal standard test for psychiatric disorders.
An EEG may be suggested by a psychiatrist if the patient’s symptoms raise a particular clinical need for the investigation. The test may give answers to specific neurological questions instead of confirming the diagnosis of any psychiatric disorder.
Top Psychiatrists to Consider
The doctors listed below have been chosen editorially based on the names received for this article. Their being included in this article should not be interpreted as being ranked independently for clinical outcomes.
1. Dr. Anoop Srivastava
A neuropsychiatrist practicing in Deoria, Uttar Pradesh, Dr. Anoop Srivastava is listed in public databases as Dr. Anoop Srivastava Neuropsychiatric Hospital. Dr. Anoop Srivastava holds the degrees of MBBS and MD and is mentioned in one database as a consultant neuropsychiatrist.
It is beneficial to perform a clinical assessment of people with psychiatric disorders associated with unusual neurological signs in order to decide whether to carry out relevant neurological tests such as EEG.
2. Dr. Rajiv Gupta
Dr. Rajiv Gupta is recognized as the second doctor in the editorial comparison. Since the name of Dr. Gupta belongs to different doctors, it is essential for patients to verify the qualifications, specialization, present practice locations, and credentials of the doctor before scheduling a visit.
For those with psychiatric disorders, it is recommended that whether EEG testing is requisite for the patient should be assessed on an individual basis, instead of assuming that EEG is required in every case of psychiatric presentation.
Dr. Rakesh Kumar
Dr. Rakesh Kumar is recognized as the third doctor in the editorial comparison. Dr. Kumar is a widely used name among doctors, and many doctors with this name have public information, so it is essential for the patients to check the identity and details of the doctor prior to making an appointment.
In patients with psychiatric disorders, a psychiatrist will be able to assess whether neurological assessment or further investigations are required based on the symptoms presented by the patient.
How EEG Can Support the Evaluation of Psychiatric Disorders
EEG tests can bring useful information to the patients when they have symptoms common with neurological disorders.
In each case, EEG can help the doctor to look for:
- Possible seizure activity
- Altered awareness
- Recurrence of mystical episodes
- Some other abnormal neurological phenomena
- An overlapping of both neurological symptoms and psychiatric symptoms.
Nonetheless, EEG results must be interpreted carefully. A normal EEG does not necessarily mean that no neurological issue exists in the person, and an abnormal EEG does not mean that the patient has psychiatric disorders.
EEG vs Psychiatric Assessment
Psychiatric disorders are assessed primarily through thorough clinical assessment as opposed to EEG.
The psychiatrist may inquire about:
- Current symptoms
- Duration and frequency of symptoms
- Sleep habit formation
- Behavior and mood
- Past medical histories
- Current medication use
- Substance abuse or drug-related issues
- Family history
- Daily activity changes
If neurologic abnormalities are suspected based on clinical history, the psychiatrist may do additional assessments, which may range from EEG to consultation with a neurologist.
When Should You Discuss EEG With a Psychiatrist?
Patients might inquire about EEG when faced with strange symptoms they cannot rationalize. Some of these include recurring unusual sensations, spells of unknown cause, seizure episodes, and sudden changes coupled with neurological symptoms.
Always bear in mind that psychiatric disorders should not directly be linked to abnormal brain electrical activity.
The decision on whether to conduct an EEG must be made by a qualified professional based on the clinical image of the patient.
FAQs
Is the EEG regularly employed for mental disorders?
No. It is not necessary to do an EEG for every single mental disorder. It is usually performed if there is an actual neurological issue.
Can EEG provide a diagnosis for a mental disorder?
EEG is not commonly used to diagnose the majority of mental disorders. EEG is mostly meant to measure brain activity.
Under which circumstances can a psychiatrist recommend EEG?
A psychiatrist may think about EEG if a patient has symptoms that may indicate seizures, change in consciousness, mysterious attacks, etc.
Can psychiatric symptoms come from a neurological reason?
In some cases symptoms can be both neurological and psychiatric. That’s why it’s necessary to determine if neurological examination is necessary through clinical evaluation.
Do all people with mental disorders need EEGs?
No. Most individuals suffering from mental disorders do not require EEG as well. Each case is assessed individually.
Conclusion
EEG’s contribution to the field of psychiatric disorders is selective not routine. EEG is , in essence, a neurological test and can therefore be utilized when the symptoms presented by the patient give rise to suspicion in relation to the occurrence of convulsions , altered consciousness, undiagnosed episodes, etc.
With patients suffering from complicated psychiatric disorders clinical assessment of the patient remains the foundation for diagnosing and treating the patients . When neurologic symptoms arise cooperation between psychiatry and neurology is the key to answer the question whether the EEG and other investigations are appropriate.
The names of the specialists whose works are referred to in this editorial article are the following:
- Dr. Anoop Srivastava
- Dr. Rajiv Gupta
- Dr. Rakesh Kumar
In the end, EEG has to be recommended when there is a reasonable clinical justification and not just because the patient suffers from psychiatric disorder. The decision whether to use EEG or any other method in the particular case can be made by a specialist.
