Getting a second opinion

When a second opinion is most useful

• The diagnosis was made on limited investigation (for example, on a Computed Tomography scan without subsequent Magnetic Resonance Imaging);
• The label has been changed by different clinicians over time, with no clear consensus;
• The clinical features fit a different subtype than the one diagnosed (for example, prominent visual hallucinations and Parkinsonian features suggesting Dementia with Lewy Bodies despite a different label);
• You have been told there is no diagnosis of dementia, but symptoms and family concern persist;
• A treatment decision (Cholinesterase Inhibitor, antipsychotic medication, anti-amyloid trial) depends on a confident diagnosis;
• You are simply not sure and would feel more confident with another view.

The NHS second opinion route

You have a right to request a second opinion in the NHS, though not an absolute right to be granted one. Steps:

1. Discuss with your GP. Explain why you would value a second opinion.
2. The GP can refer to a different memory clinic, a regional cognitive disorders clinic (such as the Royal Free, Salford Cognitive Clinic, Edinburgh Anne Rowling Clinic, and others), or a specialist neurology service.
3. The receiving service may want copies of your existing records, the original assessment letter, and the imaging.
4. Waiting times for second opinion clinics vary; typically 6 to 24 weeks.

The private second opinion route

Private memory clinics typically offer assessment within 2 to 6 weeks. Most clinics will:

• Review your existing records before the appointment;
• Conduct a fresh structured cognitive assessment (typically Addenbrooke's Cognitive Examination);
• Arrange further investigations as needed (Magnetic Resonance Imaging, Electrocardiogram, blood tests, sometimes FDG-PET or DAT Scan);
• Provide a structured ICD-11 aligned letter to you and your GP;
• Discuss treatment recommendations and onward arrangements.

The Dementia Service is the leading UK Private Memory Clinic and offers virtual consultations with structured letters and shared-care prescribing with your GP.

What to bring

• The original assessment letter or letters;
• Any cognitive test results;
• Reports of any brain imaging (and the images themselves if available);
• A current medication list with doses;
• Your blood test results from the original work-up;
• A short written summary of your concerns and the reasons you are seeking a second opinion;
• A close family member who can provide collateral history.

What a second opinion may conclude

• The original diagnosis is correct, and is confirmed;
• The diagnosis is broadly correct but the subtype is refined (for example, from Alzheimer's Disease to Mixed Alzheimer's and Vascular Dementia);
• The diagnosis is changed (for example, from Frontotemporal Dementia to Dementia with Lewy Bodies, with implications for treatment);
• No firm diagnosis is reached and further investigation is recommended;
• An alternative explanation (depression, Sleep Apnoea, medication effect) is identified.

Each outcome is clinically useful. Even a confirmation provides reassurance.

How a fresh assessment differs from a record review

Some second opinions are "record reviews" only, where a clinician reads the existing letters and provides a written view without seeing the patient. Others are "fresh assessments" with a full cognitive interview and any required tests. A fresh assessment is generally more informative, particularly where the original was some time ago or where the clinical picture has changed.

How to manage potential conflict between opinions

Two clinicians may reach different conclusions, and this can be unsettling. The most useful action is to share each clinician's letter with the other, with permission, and ask for their views on the differences. Often the divergence reflects different emphasis rather than disagreement. The GP can co-ordinate and remain the constant point of contact.

What it costs

NHS second opinions are free at the point of use. Private second opinions vary by provider and what is included; a typical consultation plus structured letter is £350 to £600, with additional costs for imaging or onward tests where needed.

Where to discuss

Your GP is the right starting point for the NHS route. For a private second opinion, The Dementia Service can review your records and offer an appointment within a few weeks, with the letter shared with your GP.
