• Neuropsychiatric Evaluation & Cognitive Assessment (Initial Screening/Referral): Initial assessment of cognitive function and neuropsychiatric symptoms, with referral for detailed neuropsychological testing if indicated, to differentiate psychiatric from neurological conditions.

Medically necessary consultations, diagnostic assessments, and medication management provided by a licensed Psychiatrist like Deroche are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. Coverage for psychotherapy services provided by a psychiatrist can vary; some provinces cover it, while others may have limitations or it may be part of hospital-based programs. Specific medications may also require special authorization or be subject to formulary restrictions. It's crucial to discuss coverage specifics for therapy or any specialized treatments with Deroche's office or Ontario Health Insurance Plan (OHIP).

Do I need a referral to see Deroche, a Psychiatrist?

Yes, a referral from your family physician or another medical doctor (e.g., a pediatrician for child psychiatry, or an ER physician for urgent assessment) is almost always required to see a Psychiatrist such as Deroche for services covered by the provincial health plan. Mental health conditions often benefit from initial assessment by a primary care provider who can determine the need for specialist psychiatric care. The referral ensures coordinated care, appropriate triaging, and transfer of relevant medical history.

When should someone consider a referral to a Psychiatrist like Deroche?

A referral to a Psychiatrist like Dr. Deroche is typically considered when mental health symptoms are severe, persistent, complex, or not responding adequately to initial treatments provided by a family doctor or therapist. This can include: thoughts of suicide or self-harm; severe depression or mania; psychosis (hallucinations, delusions); debilitating anxiety or panic attacks; complex PTSD; severe OCD; suspected bipolar disorder or schizophrenia; treatment-resistant depression; or when medication management by a specialist is indicated. Psychiatrists are also consulted for diagnostic clarification and comprehensive treatment planning, especially for co-occurring conditions.

How can I prepare for my first appointment with Deroche?

For your first psychiatric appointment with Deroche, it's helpful to gather some information beforehand. Try to make a list of your main concerns, symptoms (including when they started, how often they occur, and their intensity), and any significant life events or stressors. Bring a list of all current medications (psychiatric and non-psychiatric), including dosages, as well as any past psychiatric medications you've tried and your experience with them. Information about your family history of mental health conditions can also be very useful. Be prepared to discuss your personal history, social situation, and coping strategies. Writing down any questions you have for Deroche can also ensure you get the most out of your consultation.

Does Deroche offer psychotherapy (talk therapy)?

Many psychiatrists, including potentially Deroche, are trained in various forms of psychotherapy (talk therapy) and may offer it as part of their treatment approach, either as a standalone treatment or in combination with medication. The specific types of psychotherapy offered can vary (e.g., Cognitive Behavioral Therapy - CBT, psychodynamic therapy, supportive therapy). It's best to inquire directly with Deroche's office or discuss this during your initial consultation to understand his approach to therapy and if it's a service He provides or if He would refer you to another mental health professional like a psychologist or social worker for more intensive or specialized psychotherapy if needed.

What if I experience side effects from medication prescribed by Deroche?

It's common for psychotropic medications to have potential side effects, especially when starting a new medication or adjusting a dose. Deroche will discuss common side effects to watch for. If you experience side effects, it's very important to communicate this to Deroche or his office promptly. Do not stop taking your medication suddenly unless instructed to do so by Deroche, as this can sometimes cause withdrawal symptoms or a worsening of your condition. Deroche can help manage side effects by adjusting the dosage, switching to a different medication, or suggesting strategies to mitigate them.
