Preoperative anxiety in patients before radiosurgery treatment by Gamma Knife

<p><strong>Introduction.</strong> The work is aimed at familiarizing readers with the results of a study of preoperative anxiety in patients admitted for radiosurgical treatment (RST) using the Gamma Knife device. <strong>The aim</strong> is to study the severity and characteristics of anxiety. <strong>Materials and methods.</strong> The sample consisted of 335 patients aged 19 to 73 years (M = 50.26 years; SD = 13.45 ), of which 247 women (73.7%) and 88 men (26.3%). The group included patients with benign brain tumors (meningiomas, vestibular schwannomas, pituitary adenomas; N = 145), metastatic brain lesions (due to malignant neoplasms of the breast, lung, gastrointestinal tract, kidney, and melanoma; N= 125), vascular diseases (arteriovenous malformations, cavernomas; N = 57) and functional disorders (trigeminal neuralgia, Parkinson’s disease; N = 8). The study was conducted using a clinical psychological interview and the Hamilton Anxiety Rating Scale (HARS) questionnaire. <strong>Results.</strong> The results revealed that 66.3% of patients had severe anxiety, 31.3% had moderate anxiety, and only 2.4% of patients had no signs of pre-procedural anxiety. The average anxiety score for the entire group was 24.4 points (SD = 9.4) and corresponded to the borderline value between moderate and highly expressed anxiety. Anxious experiences manifested themselves in most patients at both the mental and somatic levels. The content of the anxious experience was associated not only with the upcoming procedure, but also reflected the situation of the oncological disease. <strong>Conclusions.</strong> The results obtained make it possible to talk about the need for psychological support for patients admitted for radiosurgical treatment.</p>
