ALZHERMERS SYNDROME in simple terms
In these diseases, neurons- the brain cells responsible for receiving, processing, and transmitting information- die and are not replaced.
The current scientific literature makes one thing plain. As yet, there is no unifying hypothesis for the causes of Alzheimer's disease, Parkinson's disease, or many rarer degenerative brain diseases that cause dementia

Are the dead neurons in the cortex replaced by new neurons?
No, dead neurons in the cortex are not typically replaced by new neurons. The brain has limited capacity for neurogenesis, especially in the cortex. Dead neurons are usually not replaced, but the brain can adapt and reorganize to compensate for lost function through processes like synaptic plasticity.
Can neurons be replaced easily?
Neurons cannot be easily replaced because they have limited regenerative capacity compared to other types of cells in the body. In the central nervous system, such as the brain and spinal cord, the ability of neurons to regenerate is restricted, making it difficult to replace damaged or lost neurons. However, in certain parts of the peripheral nervous system, such as nerves outside the brain and spinal cord, some regeneration can occur under certain conditions.
Are damaged olfactory neurons replaced?
Yes, damaged olfactory neurons can be replaced. The olfactory system has a remarkable ability to regenerate; olfactory sensory neurons are continuously renewed from basal stem cells located in the olfactory epithelium. This regeneration process allows the olfactory system to recover from injury or damage, although it may not always restore complete function.
In what ways are neurons similar to other cells?
Neurons vs. Other Cells Similarities with other cells:Neurons and other body cells both contain a nucleus that holds genetic information.Neurons and other body cells are surrounded by a membrane that protects the cell.The cell bodies of both cell types contain organelles that support the life of the cell, including mitochondria, Golgi bodies, and cytoplasm.Differences that make neurons unique:Unlike other body cells, neurons stop reproducing shortly after birth. Because of this, some parts of the brain have more neurons at birth than later in life because neurons die but are not replaced. While neurons do not reproduce, research has shown that new connections between neurons form throughout life.Neurons have a membrane that is designed to sends information to other cells. The axon and dendrites are specialized structures designed to transmit and receive information. The connections between cells are known as a synapses. Neurons release chemicals known as neurotransmitters into these synapses to communicate with other neurons.
Sensory neurons are also known as?
Afferent Neurons
Do neurons get replaced in the human brain?
No, neurons in the human brain do not typically get replaced. Once neurons are damaged or lost, they are not usually regenerated or replaced by new neurons.
Are neurons replaced in the human brain?
No, neurons are not typically replaced in the human brain. Once neurons are damaged or lost, they are not usually regenerated or replaced.
Can neurons be replaced in the human brain?
No, neurons cannot be replaced in the human brain. Once neurons are damaged or lost, they typically cannot regenerate or be replaced.
Are the dead neurons in the cortex replaced by new neurons?

Dead neurons are usually not replaced, but the brain can adapt and reorganize to compensate for lost function through processes like synaptic plasticity.
Do neurons have the ability to replicate?
No, neurons do not have the ability to replicate. Once they are damaged or lost, they cannot be replaced.
What cells in your body are never replaced?
Neurons in the brain and spinal cord are cells in the body that are never replaced.
Can neurons be replaced easily?

Why does tau overexpression and deposits of amyloid beta protein inside and between neurons cause the neurons to die?
