There is no set amount of brain lesions that occur with progressive multifocal leukoencephalopathy. The amount can range from one to several and will vary depending on the amount of damage the virus which causes the disease has a chance to do.
Progressive multifocal leukoencephalopathy (PML) is a rapidly progressive neuromuscular disease caused by opportunistic infection of brain cells
Multifocal signal intensity lesions on the brain refer to areas of abnormal signal intensity seen on an MRI scan that appear in multiple locations throughout the brain. These lesions can be caused by various conditions such as multiple sclerosis, infections, or inflammatory disorders. Further evaluation and testing are usually needed to determine the underlying cause of these lesions.
This means that there are multiple areas of involvement of a lesion or disease. (As an example, multifocal leukoencephalopathy means that there are a number of areas in the brain which have white patches on them, causing a delirium or confusional syndrome.)
Small foci of demyelination in both hemispheres of the brain can be caused by conditions such as acute disseminated encephalomyelitis (ADEM), neuromyelitis optica (NMO), leukodystrophies, and infections like progressive multifocal leukoencephalopathy (PML). These conditions can present with similar patterns of demyelination to multiple sclerosis (MS) but have distinct underlying causes and clinical features. A detailed evaluation by a neurologist and additional tests such as MRI, lumbar puncture, and blood tests are typically needed to differentiate between these conditions.
Progressive multifocal leukoencephalopathy (PML) is a neurological disorder characterized by destruction of the myelin, an oily substance that helps protect nerve cells in the brain and spinal cord, also known as central nervous system (CNS) white matter. PML occurs in approximately one in 200,000 people.
Opportunistic infections of the brain such as progressive multifocal leucoencephalopathy (PML) and meningitis, other opportunistic infections such as herpes zoster (shingles ), peripheral neuropathy , depression , and AIDS-related dementia.
No, scalp lesions affect the skin and hair of the scalp. What happens on the scalp does not permeate the brain. The brain is under the skull bones. The lesions cannot get through the skull to the brain.
It is not dementia that causes brain lesions. It is the brain lesions that could have caused Dementia. Dementia Praecox was the type of dementia that involved brain lesions post mortem. You can try to read passages from the "Dementia Praecox Studies: A Journal of Psychiatry of Adolescence," (1920 Vol. 3-4 by Holmes, B.T.)
Eating disorders have been sometimes considered to be associated with brain lesions, see links below.
These are called lesions. Brain lesions can be caused by injury, infection, exposure to certain chemicals, problems with the immune system, and more. Typically, their cause is unknown.These are called lesions. Brain lesions can be caused by injury, infection, exposure to certain chemicals, problems with the immune system, and more.

The signs and symptoms of AID's are practically identical to the signs and symptoms of HIV, its predecessor, which include; Skin Effects: -Herpes Simplex Virus (HSV) -Varicella Zoster Virus (VZV) -Kaposi's Sarcoma (KS) Oral Health Problems: -Candidiasis -Peridontal Disease -Herpes Simplex Virus Neurological Effects: -Dementia -Decrease in the ability to think properly and process information -Brain Tumors -Progressive Multifocal Leukoencephalopathy HIV/AIDs positive patients may also experience an unintentional weight loss of approximately 10%.
