Electroencephalography in Astana: 1 doctor

Key points

• The recording lasts from forty minutes to an hour and does not require hospitalisation.
• The method shows the electrical activity of the brain, but does not detect tumours, cysts or the consequences of injuries.
• The referral is given by a neurologist, who also compares the report with the complaints and the examination.
• Before the visit, the hair should be clean, without hairspray, gel or styling products.
• A repeat recording is prescribed by the attending physician; there is no fixed schedule for everyone.

What is electroencephalography

Electroencephalography is a method of studying the bioelectrical activity of the brain that helps assess how it works at rest and under various loads. A doctor prescribes the procedure when it is necessary to understand the cause of seizures, sleep disturbances or unusual behaviour.

What the service gives the doctor and the patient

Electroencephalography gives the doctor an objective picture of the brain's electrical signals, which cannot be assessed during a routine examination. During the recording, rhythms of different frequencies, their amplitude and symmetry between the hemispheres are registered. The specialist sees whether there are areas with altered activity characteristic of epileptic discharges or focal disorders. The patient receives a clear explanation of why seizures, memory lapses or episodes of freezing occur. For a neurologist, this is the basis for distinguishing true epilepsy from fainting, panic attacks and sleep disorders. The result helps choose the right management strategy and decide whether additional examinations are needed. If the recording is calm, that is also valuable: it removes unnecessary worries and narrows the search. That is why the interpretation is always compared with the complaints and the examination, and is not read separately from the patient's history.

When the service is prescribed

• Epileptic seizures: recurring convulsions or loss of consciousness require confirmation that the cause lies precisely in brain activity.
• Fainting of unclear origin: if a person suddenly falls for no understandable reason, the recording helps rule out hidden discharges.
• Sleep disorders: in cases of night awakenings, sleepwalking or breathing pauses, brain activity is assessed in different phases of rest.
• Developmental delay in a child: when speech, movements or behaviour lag behind those of peers, the method clarifies the state of brain functions.
• Consequences of injuries and strokes: after damage it is important to see how the electrical activity has recovered and whether there are focal changes.
• Monitoring the course of the disease: a repeat recording shows the dynamics, so it is prescribed when complaints change or the condition worsens.

What this service will not show

Electroencephalography does not show the structure of the brain, so it will not detect a tumour, a cyst or the consequences of an injury. For this, tomography or magnetic resonance imaging is needed, which provide an image of the tissues. The method does not determine the cause of mental disorders and does not replace a conversation with a psychiatrist or psychologist. It does not measure memory, attention and intelligence: separate neuropsychological tests exist for this. The recording does not confirm or rule out migraine, tension headache or dizziness — these conditions are assessed clinically. A normal picture in the presence of complaints does not mean that the person is healthy: it only indicates the absence of characteristic discharges at the time of the examination. That is why the result is always read together with the examination and other data, and if there are doubts the doctor prescribes additional methods.

How does the procedure go?

Electroencephalography in Astana is performed in a functional diagnostics room and takes from forty minutes to an hour. Below is a description of the stages the visit consists of and what a person feels during the recording.

Step-by-step course of the procedure

Electroencephalography begins with the patient being seated in a comfortable chair or laid on a couch in a quiet room. The specialist puts an elastic cap with electrodes on the head or attaches them with small clips to the skin. Before placement, the contact sites are degreased and a conductive gel is applied so that the signal passes without interference. Then the recording is switched on, and the person is asked to relax, close their eyes and lie still. As the examination proceeds, short tasks are given: to breathe deeply, to open and close the eyes, to look at flashes of light. The doctor monitors the curves on the screen and notes the moments when brain activity changes. After the electrodes are removed, the head is wiped, and the recording is processed and drawn up into a written report.

How long each stage takes

What the patient feels

Electroencephalography does not cause pain, since the electrodes only touch the skin of the head and do not pass current through the body. The most noticeable sensation is the coolness of the gel at the moment of application and the slight pressure of the cap on the top of the head. During the recording, the person lies with their eyes closed and hears only the steady noise of the machine and the voice of the specialist. The deep-breathing test may cause dizziness or tingling in the fingers, but this passes quickly. Flashes of light are perceived as short bright impulses, to which there is no need to react. After the sensors are removed, there remains a wish to wash one's head, because the gel dries and tightens the skin. Take a comb and a towel with you to tidy your hair right after the room.

Preparing for the procedure

Preparation for an electroencephalography in Astana starts at home and takes only a few hours. How calmly this time passes determines whether it will be possible to record a clean trace without interference.

What to do the day before

Electroencephalography is sensitive to the condition of the scalp, so the hair should be clean before the procedure. It is best to wash your hair in the evening or in the morning on the day of the visit, but without conditioners, masks or styling products. Residues of hairspray, gel or dry shampoo create a film that makes the electrodes hold worse and produces extra interference on the recording. A heavy dinner and strong coffee the day before are also undesirable: they change the brain rhythms and make the result harder to read. If the doctor has not cancelled your usual medicines, take them as usual, otherwise changes will appear on the trace that are not present in everyday life. Sleep on the night before the examination should be normal, without sleep deprivation and without trying to catch up on a week's sleep in advance. Take a comb with you and, if you wear them, spare glasses or contact lenses — they make it easier to fill in documents after the visit.

What to bring with you

• Referral: a form from the attending doctor stating the purpose of the examination is needed so that the specialist can choose the correct recording mode and position the electrodes properly.
• Identity document: an ID card or passport will be needed for registration at the reception desk and to confirm that the examination is being performed on you.
• Previous reports: earlier electroencephalogram recordings, if they have been kept, help the doctor see the dynamics and not lose important details.
• Discharge summaries and scans: the results of examinations, neurologist's reports and brain scans provide context without which a single trace is harder to read.
• List of medicines taken: a list of names and dosages written on a sheet will be useful to the doctor when interpreting the results and will save you from inaccurate recollections.
• Comb and towel: after the electrodes are removed, gel remains on the hair, and the opportunity to tidy yourself up before leaving the room turns out to be far from unnecessary.

What not to do

• Come with unwashed hair: grease and cosmetic products on the skin increase resistance, which makes the recording noisy and requires a repeat visit.
• Drink coffee and energy drinks: stimulating drinks change the pattern of rhythms, and the doctor sees changes that you do not have in your usual state.
• Cancel prescribed treatment on your own: the decision to take or skip medicines is made only by the attending doctor, otherwise the interpretation loses its meaning.
• Arrive in a state of severe stress: anxiety and haste before the room are reflected in the trace, so it is worth setting out early and not rushing on the way.
• Hide feeling unwell: you should mention a recent cold, fever or a sleepless night in advance so that the visit can be postponed if necessary.

Who gets it and how often?

In Astana, electroencephalography is most often needed by neurologists and epileptologists, who assess the functioning of the brain. Let us look at which patients are regularly prescribed it and what determines how soon the investigation is repeated.

Who is prescribed it most often

Electroencephalography is most often prescribed to patients with suspected epilepsy or with an already established such diagnosis. The reason is that the method directly records the bioelectrical activity of the brain and helps distinguish epileptic activity from other conditions. The second large group consists of people after fainting, seizures with loss of consciousness or unexplained convulsions, when their nature needs to be understood. It is also undergone by children with delayed speech and mental development, if the doctor is looking for changes in brain function. Patients after traumatic brain injuries, strokes and neurosurgical operations need it to monitor recovery. People with frequent and severe headaches, dizziness and sleep disturbances also fall into this group, when other examinations have not provided an answer. The indications for the procedure are always determined by the attending physician based on the combination of complaints, examination and data from other investigations. If the seizures recur, do not postpone a visit to a neurologist: recording brain activity during a seizure is especially informative.

When it is done and when it is postponed

How often it is repeated

The frequency of repeat electroencephalography is determined by the attending physician, and not by a fixed schedule or the patient's wish. When changes are detected for the first time, the recording is usually repeated after observation begins, in order to see the dynamics against the background of the measures being taken. If the seizures persist or change in character, the interval between investigations is shortened, and the recording itself may be done with functional tests. With a stable condition and no seizures, control recordings are performed less often, sometimes once every few months or on special occasions. In children with developmental delay, the recording is often repeated as they grow, since the picture of brain activity changes with age. Before neurosurgical intervention and after it, the timing is set by the operating physician, based on the task of the stage. It is useful for the patient to keep all previous reports and show them at each new investigation. This helps the doctor compare the curves and assess changes more accurately, rather than looking at a single recording in isolation from the history.

Electroencephalography in Astana: clinics and doctors

In Astana, electroencephalography is performed in medical centres of various profiles, and it is more convenient to make a choice using the clinic cards. Below is how the selection for this service works and what signs to look at.

How many clinics offer the service

Electroencephalography in Astana is presented in the catalogue of clinics, where appointments in this area are conducted by one doctor. The cards are gathered in one place, so you do not have to call the centres one by one and check whether they have the right specialist. Each clinic has an address, and the doctor has a profile showing whether he works with brain examinations. The appointment schedule helps you understand on which days you can come and how the visit time is coordinated. Visitor reviews add lively impressions to the dry data about how the appointment is organised and how attentively they communicate with the patient. If the referral is given by the attending doctor, the card makes it easy to check whether the specialist's profile matches what is stated in the referral. Such a set of information saves time at the search stage and reduces the risk of ending up with the wrong specialist. Before calling, it is worth opening the card and writing down the address, appointment days and the doctor's name so that you can ask the administrator precise questions.

What to look at when choosing a clinic

• Doctor's profile: it states whether the specialist conducts appointments in this area, and this is the first thing to check against the referral.
• Address and district: the location of the clinic affects the journey, especially if several visits are ahead and you will have to travel regularly.
• Appointment schedule: the days and hours show whether it will be possible to combine the visit with work or study without rearranging the week.
• Visitor reviews: they describe the organisation of the appointment and communication with the staff, which is not visible from the formal data on the card.
• Completeness of the card: filled-in fields indicate that the clinic keeps its information up to date.

What is shown on the clinic card

The clinic card gathers in one place the address, information about the doctors, the appointment schedule and visitor reviews, and these fields make it convenient to compare centres with each other. The address shows the district of the city, so it is immediately clear how long the journey will take and whether there are convenient entrances. In the section about the doctors, the specialist conducting appointments in this area is indicated, and his profile helps to check whether it matches what is written in the referral from the attending doctor. The schedule answers the question of on which days and hours you can come, and also how easy it is to coordinate the visit with your work schedule. Reviews complement the formal data: in them, visitors describe how the appointment is organised and how the conversation with the specialist is conducted. If some fields are only partially filled in, this is a reason to clarify the details by phone before the journey. Before the visit, it is worth writing down the address, the doctor's name and convenient appointment days so that you can ask the administrator precise questions and not ask the same thing again.

How to book an appointment?

You can book an electroencephalography in Astana via the form on the service page by choosing a convenient date and time. Below — how to fill in the request, what happens after it is sent and what you should prepare in advance.

How to submit a request

The request for an electroencephalography in Astana is filled in directly on the service page, without registration or creating a personal account. First you choose a convenient date and time from the available options in the calendar, and then enter your name and phone number in a short form. The name and phone fields are mandatory, so the request will not be sent without them. The phone number is needed for confirmation, so enter the one that is always at hand. After the form is sent, a notification appears on the screen that the request has been accepted. Booking an appointment in Astana takes a couple of minutes if the details are entered without typos. Check the phone number before sending: an error in one digit will mean the confirmation does not arrive.

What happens after the request

What you will need for the booking

• Name: enter it as it is written in your documents, so that the administrator processes the request without errors and does not have to ask again.
• Phone: a current number to which the confirmation will be sent, so check it before sending the form.
• Date and time: choose a slot when it is convenient for you to come, so that you do not have to reschedule the visit later.
• A calm environment: fill in the form without rushing, so as not to make a mistake in the digits of the number and not to wait for confirmation again.
• Access to messages: keep your phone nearby so that you can read the confirmation straight away and reply if clarification is needed.

What is worth remembering

Electroencephalography in Astana remains an investigation that requires a calm and informed decision from the person. Below is what is worth keeping in mind when the referral has already been received.

Key takeaways

Electroencephalography in Astana gives the doctor an objective picture of the brain's electrical activity, rather than a subjective description of how the person feels. The referral is issued by the treating doctor, and it is he who formulates the question that the investigation must answer. The procedure itself is painless and carries no risk, so there is no point in putting it off because of worries. Preparation comes down to simple everyday matters: clean hair, comfortable clothing, a calm state and no rushing before the consulting room. The result is described by a specialist, and not straight away, but after reviewing the entire recording as a whole. The finished report goes back to the doctor who referred the person, and only he compares the data with the complaints and history. If the report seems unclear, it is sensible to ask questions of the referring doctor rather than seek an interpretation on one's own.
