Magnetstimulatsioon

Magnetstimulatsioon, often referred to as magnetic stimulation, is a non-invasive neuromodulation technique used to influence brain activity. It involves the application of focused magnetic pulses to specific areas of the brain. These magnetic pulses can pass through the skull and induce electrical currents in the underlying neural tissue. This induced electrical activity can either excite or inhibit the targeted neurons, thereby altering their firing patterns and affecting brain function.

The most common form of magnetstimulatsioon is repetitive transcranial magnetic stimulation (rTMS). This technique delivers a series of rapid magnetic pulses. The frequency and intensity of these pulses can be adjusted to achieve different therapeutic effects. Low-frequency rTMS is generally inhibitory, while high-frequency rTMS is typically excitatory.

Magnetstimulatsioon has shown promise in the treatment of various neurological and psychiatric disorders. It is FDA-approved for the treatment of major depressive disorder, obsessive-compulsive disorder, and for aiding smoking cessation. Research is ongoing into its potential applications for conditions such as Parkinson's disease, stroke recovery, chronic pain, and schizophrenia. The exact mechanisms by which magnetstimulatsioon exerts its therapeutic effects are still being investigated, but it is believed to involve changes in synaptic plasticity and the modulation of neural networks. The procedure is generally well-tolerated, with side effects typically being mild and transient, such as headache or scalp discomfort.
