Degeneration of brain cells resulting from disease in the brain’s arteries, leading to what’s termed “brain softening.” Symptoms include the patient being irritable, self-centered, moody, and easily fatigued. Conversations may slow, and they may exhibit depression or paranoia. Complaints can range from headaches, dizziness, ear noises, to fainting and sleeplessness. There might be speech and writing disturbances, and memory decline. Notably, even when mildly affected, the patient may still appear normal and rational. Emotional regulation diminishes, leading to outbursts or exaggerated claims, such as not having slept for weeks. A sudden change in environment might disrupt their facade of normality, causing them to break down. This condition is also referred to as Alzheimer’s disease.
