What to Expect During a Psychiatric Evaluation

During the initial visit, Dr. Marinho reviews your symptoms, their duration and effect on daily functioning, medical and psychiatric history, previous medications, family history, and current life circumstances. When relevant, the evaluation includes sleep, mood, thought processes, memory, attention, substance use, and risk of harm to self or others.

After the assessment, the doctor explains the working or confirmed diagnosis and recommends a treatment plan. This may include medication, psychotherapy, selected lifestyle measures, additional testing, or coordinated care with a psychologist or another medical specialist.

Medication Management

A psychiatrist can prescribe medication, assess treatment response and side effects, adjust doses, and modify a medication plan safely when needed. Medication decisions are individualized after a clinical assessment; seeking psychiatric care does not automatically mean that medication will be prescribed.

If you are already taking psychiatric medication, bring a current list with doses and information about previous treatments. Do not abruptly stop prescribed medication without medical guidance.

Psychotherapy Training

Dr. Marinho holds Level A certification in Interpersonal Psychotherapy and postgraduate qualifications in couples therapy and clinical sexology. Her additional training includes grief intervention, crisis care, psychosis, and perinatal mental health.

A psychiatric appointment and a course of regular psychotherapy are different forms of care. The need for psychotherapy, the most appropriate approach, and the treating professional are determined individually; ongoing psychotherapy may be scheduled as a separate service.

Adolescent Psychiatry

At UMC, Dr. Marinho sees adolescents aged 14 and older. Reasons for an evaluation may include anxiety, depressive symptoms, self-harm, sleep or eating problems, marked changes in mood or behavior, obsessive symptoms, declining school performance, or difficulty with social adjustment.

Parent or legal guardian participation depends on the patient’s age, the clinical situation, and applicable consent and confidentiality rules. Please confirm the arrangements when booking.
