Dementia is a result of a loss of cognitive brain function. The disease happens gradually with a loss of connections of brain neurons or in more simple terms: the neurons just stop working. The non-function of brain neurons is normal as people age. However, with dementia these neuron losses are accelerated much more quickly.
Signs of a person developing dementia include but are not limited to memory loss, language skills, visual impairment, and the ability to focus. Additionally, a person who has developed dementia may develop different personality traits such as emotional outbursts, paranoia, delusions, or hallucinations.
Currently, there is no cure for dementia and its related diseases such as Alzheimer’s. There are medicines available to slow down or treat symptoms but the continual loss of brain neuron function cannot be controlled by current medicine.
