Clinical focus

The areas of clinical interest of Feyza Ağaç Çelebi cover a range of mood and anxiety conditions. These include depression, bipolar disorder and panic disorder, as well as obsessive-compulsive disorder (OCD) and illness anxiety disorder, also known as hypochondriasis. She also works with people affected by post-traumatic stress disorder, offering psychological support to those coping with the after-effects of a distressing experience. In each case, the psychological approach is adapted to the individual’s history, current symptoms and personal circumstances, and is discussed openly with the patient before it begins.

Sleep disorders form another part of her clinical focus, including insomnia, sleep apnea and circadian rhythm disturbances, with melatonin-related approaches considered where appropriate within the wider care team. In addition, she sees individuals and couples dealing with relationship problems and marital problems. Neuropsychological assessment is also part of her practice; this involves a structured evaluation of cognitive functioning that can support diagnosis and treatment planning alongside psychiatric colleagues.

How Feyza Ağaç Çelebi works with international patients

Feyza Ağaç Çelebi sees international patients in İstanbul. Before the visit, the Acibadem international patient team coordinates the collection of prior reports, including previous psychological or psychiatric evaluations, discharge summaries, laboratory results and any relevant imaging reports, and arranges appointments as well as the hospital visit itself. A first consultation typically covers the patient’s history and current symptoms, a review of previous assessments and treatments, a clinical evaluation and a discussion of the possible options. Because psychological work depends on clear communication, interpreters can be arranged when needed, so that patients can describe their concerns in the language in which they feel most comfortable.
