Frequently Asked Questions (FAQs)

What can I do with a Level 3 mental health, dementia and learning disabilities diploma?

This diploma helps you work with more confidence as a care worker, support worker, healthcare assistant or residential support worker. It deepens your knowledge of all three areas and adds a CPD certificate to your training record. It is also a useful step towards senior carer or team leader roles, or further study in adult care.

What are the early signs of dementia?

According to the NHS, common early signs of dementia include memory loss, difficulty concentrating, finding familiar daily tasks hard, struggling to follow a conversation or find the right word, confusion about time and place, and mood changes. Dementia is not a natural part of ageing, so anyone worried about these symptoms should speak to a GP early.

What are the main types of dementia?

The main types of dementia are Alzheimer’s disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia. Alzheimer’s disease is the most common cause of dementia in the UK. Around one million people in the UK live with dementia, and this is expected to rise to 1.4 million by 2040, according to Alzheimer’s Society.

What are the 6 C's of dementia care?

The 6 C’s are care, compassion, competence, communication, courage and commitment. NHS England introduced them in 2012 in its Compassion in Practice strategy as core values for nurses, midwives and care staff. In dementia care, they guide how you support each person with patience, respect and clear communication.

What is the difference between a learning disability and a learning difficulty?

A learning disability affects a person’s intellectual ability and lasts their whole life, so they may need support with everyday tasks, learning and communication. A learning difficulty, such as dyslexia or dyscalculia, affects specific skills but not overall intellect. Mencap estimates that around 1.5 million people in the UK have a learning disability.

What is the difference between dementia and a learning disability?

A learning disability is present from birth or early childhood and lasts for life. Dementia is caused by diseases that damage the brain over time, so a person’s abilities decline, usually later in life. The two can occur together. For example, people with Down’s syndrome have a higher risk of developing Alzheimer’s disease at a younger age.

Why is mental health awareness important for care workers?

Mental health awareness helps care workers spot early signs of distress, respond with empathy and know when to report concerns. Mental health problems are common: Mind reports that 1 in 4 people in England experience a mental health problem each year. Early support improves outcomes and helps people stay independent for longer.

How long does it take to complete this course?

The course takes about 14 hours 44 minutes to complete, and you have 1 year of access. You can study at your own pace on a laptop, tablet or phone, so it fits around shift work. You do not need any previous care experience or qualifications to enrol.
