Brain Activity and Neurophysiological Research
Brain activity constantly changes, depending on the time of day, the individual's condition, sleep and wake cycles. Neurophysiological studies provide the most detailed information about brain function, allowing the assessment of brain wave activity, blood vessel condition, and internal structures in real-time. The functional diagnostics physician studies the central nervous system, including functions such as sensation, coordination, hearing, and smell.
Neurophysiologists identify the causes of the following issues:
• Sensory disorders
• Motor disorders
• Cerebral circulation problems
• Memory impairments
• Epilepsy
• Panic attacks
• Consequences of traumatic brain injuries
• Sleep disorders
• Headaches, dizziness, and more.
NEUROPHYSIOLOGICAL STUDIES
OKİ Hospital is equipped with the most advanced diagnostic tools, which allow for comprehensive functional research of the nervous system.
ELECTROENCEPHALOGRAPHY (EEG)
An informative method for studying the brain, which assesses the state of the nervous system by recording the bioelectric potentials of the cerebral cortex. At OKİ Clinic, patients can undergo various types of electroencephalography:
• Routine EEG
• EEG with sleep deprivation
• EEG with a 20-minute background recording followed by provoking functional tests
For the research, the patient wears a special "cap" with sensors on the head that analyze brain function. The result is an electroencephalogram that helps the doctor identify pathological areas, assess the degree of damage, determine the treatment plan, and monitor its effectiveness over time.
This study is used for evaluating and determining the causes of:
• Headaches, dizziness
• Panic attacks
• Episodes of unconsciousness with seizures
• Speech development delays in children
ELECTROMYOGRAPHY (EMG)
Electromyography is a method for diagnosing disorders of the neuromuscular system based on the bioelectrical activity of muscles. The research is based on the muscle tissue's ability to create electrical activity during each contraction. Based on the results, considering the clinical picture, the site and localization of the lesion are determined.
EMG is performed using an electromyograph. The device records bioelectric activity, transmitting it to the monitor or onto paper.
Performing electromyography helps determine:
• Localization of the pathological focus
• The nature of the pathology: whether the muscle or nerve fibers are affected
• The extent of the process
• The stage of the disease
• The level of damage: there may be a localized or systemic disease, and based on this, the type of study is chosen
• The dynamics of the pathological process
Indications for electromyography:
• Muscle weakness, increased fatigue
• Presence of seizure syndrome
• Sensitivity disturbances
• Decreased muscle volume
• Pain of varying intensity in the muscles
• Diseases requiring electromyography include:
• Polyneuropathies
• Muscle pathology: inflammation, dystrophy, increased fatigue
• Degenerative-dystrophic changes in the spine
• Hyperkinesia (involuntary muscle movements)
• Tremors in Parkinson’s disease
• Radiculopathy (damage to nerve roots)
