Autoimmune Diseases
Learn about autoimmune diseases, their symptoms, causes, and how to manage them with support from Paincation’s digital therapeutics.
Acute Disseminated Encephalomyelitis (ADEM)
Acute Disseminated Encephalomyelitis (ADEM) is a rare autoimmune disease affecting the brain and spinal cord, often triggered by infections or vaccinations. Learn about its symptoms, causes, diagnosis, and treatments.
Addison’s Disease
Addison’s disease is a rare autoimmune disorder that affects the adrenal glands. Learn about its symptoms, causes, diagnosis, and treatment options to manage this condition effectively.
Alopecia Areata
Alopecia areata is an autoimmune disorder causing hair loss in round patches on the scalp and body. Learn about its symptoms, causes, diagnosis, and treatments to help manage hair loss.
Ankylosing Spondylitis (AS)
Ankylosing spondylitis (AS) is a chronic autoimmune disease affecting the spine, causing inflammation and pain. Learn about its symptoms, causes, diagnosis, and treatment options for managing this condition.
What is Anti-GBM Disease (Goodpasture’s Syndrome)?
Anti-GBM disease, also called Goodpasture’s syndrome, is a rare autoimmune condition in which the body’s immune system mistakenly attacks the glomerular basement membrane (GBM) in the kidneys and the alveoli in the lungs.
Antiphospholipid Syndrome (APS)
Antiphospholipid syndrome (APS) is an autoimmune disorder in which the body’s immune system mistakenly produces antibodies that attack phospholipids, molecules that play a critical role in blood clotting.
Autoimmune Hepatitis
Autoimmune hepatitis (AIH) is a chronic disease in which the body’s immune system attacks the liver, causing inflammation (hepatitis).
Autoimmune Inner Ear Disease (AIED)
Autoimmune inner ear disease (AIED) is a rare autoimmune disorder in which the immune system mistakenly attacks the cells in the inner ear, leading to progressive hearing loss, tinnitus (ringing in the ears), and balance problems.
Autoimmune Myocarditis
Autoimmune myocarditis is a rare and serious condition in which the immune system attacks the heart muscle, causing inflammation and leading to heart damage. Learn about the symptoms, diagnosis, and treatment options to manage autoimmune myocarditis and prevent complications.
Achalasia
Achalasia is a rare disorder of the oesophagus (the tube that carries food and liquids from the mouth to the stomach) that makes it difficult for the oesophagus to move food into the stomach.
Adult-onset Still’s Disease (AOSD)
Adult-onset Still’s Disease (AOSD) is a rare autoimmune inflammatory disorder that affects adults, characterized by high fevers, joint pain, and a distinctive salmon-colored rash.
Agammaglobulinemia
Agammaglobulinemia, also known as X-linked agammaglobulinemia (XLA), is a rare genetic immune disorder that affects the body’s ability to produce B cells, a type of white blood cell responsible for producing antibodies.
Amyloidosis
Amyloidosis is a rare, serious condition characterised by the abnormal buildup of a protein called amyloid in tissues and organs throughout the body. When amyloid proteins accumulate, they interfere with the normal function of organs, which can lead to life-threatening complications.
Autoimmune Angioedema
Autoimmune angioedema is a rare condition where the immune system mistakenly attacks the body’s tissues, leading to sudden swelling (angioedema) in areas like the face, lips, throat, and extremities.
Autoimmune Dysautonomia
Autoimmune dysautonomia is a rare condition in which the body’s immune system mistakenly attacks the autonomic nervous system (ANS), the part of the nervous system that controls involuntary body functions such as heart rate, blood pressure, digestion, and temperature regulation.
Autoimmune Oophoritis
Autoimmune oophoritis is a rare autoimmune condition where the body’s immune system mistakenly attacks the ovaries, leading to inflammation, damage to ovarian tissue, and disruption of normal ovarian function.
Autoimmune Orchitis
Autoimmune orchitis is a rare autoimmune disorder where the body’s immune system mistakenly targets the testicles, causing inflammation and damage to testicular tissue.
Autoimmune Pancreatitis
Autoimmune pancreatitis (AIP) is a rare type of chronic pancreatitis caused by the immune system mistakenly attacking the pancreas, leading to inflammation and damage to pancreatic tissue.
Autoimmune Pulmonary Alveolar Proteinosis (aPAP)
Autoimmune Pulmonary Alveolar Proteinosis (aPAP) is a rare lung disorder where the immune system mistakenly attacks a protein called granulocyte-macrophage colony-stimulating factor (GM-CSF), impairing the ability of the lungs to clear out a substance called surfactant.
Autoimmune Retinopathy (AIR)
Autoimmune Retinopathy (AIR) is a rare eye disorder where the immune system mistakenly targets and attacks the retina, the light-sensitive tissue located at the back of the eye that is crucial for vision.
Autoimmune Urticaria
Autoimmune Urticaria is a form of chronic hives (urticaria) caused by the immune system attacking the body’s own tissues, leading to persistent, itchy welts on the skin.
Axonal and Neural Neuropathy (AMAN)
Axonal and Neural Neuropathy (AMAN) is a rare subtype of Guillain-Barré syndrome (GBS), a condition in which the body’s immune system mistakenly attacks the peripheral nervous system.
Anxiety
Anxiety is a natural response to stress, characterised by feelings of worry, fear, or nervousness. While everyone experiences anxiety from time to time, chronic anxiety can become overwhelming and interfere with daily life.
Augmented Reality (AR)
Augmented Reality (AR) is a technology that overlays digital content—such as images, videos, sounds, or 3D objects—onto the real world in real time.
Balo Disease
Balo Disease, also known as Balo concentric sclerosis, is a rare and severe form of multiple sclerosis (MS).
Behçet’s Disease
Behçet’s Disease is a rare, chronic autoimmune disorder that leads to inflammation of the blood vessels throughout the body. This condition, also known as Behçet’s syndrome, can affect multiple organ systems, causing a wide variety of symptoms that may range from mild to life-threatening.
Benign Mucosal Pemphigoid
Benign Mucosal Pemphigoid (BMP), also known as Cicatricial Pemphigoid, is a rare, chronic autoimmune disorder that primarily affects the mucous membranes, such as the eyes, mouth, nose, and genital areas.
