Cognitive disorders are conditions that affect a person's ability to think, learn, and remember. These disorders can impact daily life, making it difficult to perform tasks that require attention, problem-solving, or decision-making. Common examples include Alzheimer's disease and dementia, which primarily affect older adults, but cognitive disorders can also occur in younger individuals due to brain injuries or other health issues. Symptoms of cognitive disorders can vary widely, ranging from mild forgetfulness to severe confusion and disorientation. Treatment often involves a combination of medication, therapy, and support from family and friends. Early diagnosis and intervention can help manage symptoms and improve quality of life for those affected.
