The symptoms of arthritis you experience will vary depending on the type you have.
This is why it's important to have an accurate diagnosis if you have:
joint pain, tenderness and stiffness
inflammation in and around the joints
restricted movement of the joints
warm, red skin over the affected joint
weakness and muscle wasting
Arthritis and children
Arthritis is often associated with older people, but it can also affect children. In the UK, about 15,000 children and young people are affected by arthritis.
Most types of childhood arthritis are known as juvenile idiopathic arthritis (JIA). JIA causes pain and inflammation in one or more joints for at least six weeks.
Although the exact cause of JIA is unknown, the symptoms often improve as a child gets older, meaning they can lead a normal life.
The main types of JIA are discussed below. Arthritis Research UK has more information about the different types of juvenile idiopathic arthritis.
Oligo-articular JIA
Oligo-articular JIA is the most common type of JIA. It affects fewer than five joints in the body – most commonly in the knees, ankles and wrists.
Oligo-articular JIA has good recovery rates and long-term effects are rare. However, there's a risk that children with the condition may develop eye problems, so regular eye tests with an ophthalmologist (eye care specialist) are recommended.
Polyarticular JIA (polyarthritis)
Polyarticular JIA, or polyarthritis, affects five or more joints. It can develop at any age during childhood.
The symptoms of polyarticular JIA are similar to the symptoms of adult rheumatoid arthritis. The condition is often accompanied by a rash and a high temperature of 38C (100.4F) or above.
Systemic onset JIA
Systemic onset JIA begins with symptoms such as a fever, rash, lethargy (a lack of energy) and enlarged glands. Later on, joints can become swollen and inflamed.
Like polyarticular JIA, systemic onset JIA can affect children of any age.
Enthesitis-related arthritis
Enthesitis-related arthritis is a type of juvenile arthritis that affects older boys or teenagers. It can cause pain in the soles of the feet and around the knee and hip joints, where the ligaments attach to the bone.
Treating arthritis
There's no cure for arthritis, but there are many treatments that can help slow down the condition.
For osteoarthritis, medications are often prescribed, including:
painkillers
non-steroidal anti-inflammatory drugs (NSAIDs)
corticosteroids
In severe cases, the following surgical procedures may be recommended:
arthroplasty (joint replacement)
arthodesis (joint fusion)
osteotomy (where a bone is cut and re-aligned)

Treatment for rheumatoid arthritis aims to slow down the condition's progress and minimise joint inflammation or swelling. This is to try and prevent damage to the joints. Recommended treatments include:
analgesics (painkillers)
disease modifying anti-rheumatic drugs (DMARDs) – a combination of treatments is often recommended
physiotherapy
regular exercise
Although there is no cure for dementia at present, if it's diagnosed in the early stages, there are ways you can slow it down and maintain mental function. A diagnosis can help people with dementia get the right treatment and support, and help those close to them to prepare and plan for the future. With treatment and support, many people are able to lead active, fulfilled lives. The symptoms of dementia tend to worsen with time. In the much later stages of dementia, people will be able to do far less for themselves and may lose much of their ability to communicate.
