Deaths due to<unk>  conditions per million persons 2012<unk> s can be categorized according to the primary location affected, the primary type of dysfunction involved, or the primary type of cause. The broadest division is between central nervous system<unk> s and peripheral nervous system<unk> s. The Merck Manual lists brain, spinal cord and nerve<unk> s in the following overlapping categories: * Brain: * Brain damage according to cerebral lobe (see also 'lower' brain areas such as basal ganglia, cerebellum, brainstem): * Frontal lobe damage * Parietal lobe damage * Temporal lobe damage * Occipital lobe damage * Brain dysfunction according to type: * Aphasia (language) * Dysgraphia (writing) * Dysarthria (speech) * Apraxia (patterns or sequences of movements) * Agnosia (identifying things or people) * Amnesia (memory) * Spinal cord<unk> s (see spinal pathology, injury, inflammation) * Peripheral neuropathy and other Peripheral nervous system<unk> s * Cranial nerve<unk>  such as Trigeminal neuralgia * Autonomic nervous system<unk> s such as dysautonomia, multiple system atrophy * Seizure<unk> s such as epilepsy * Movement<unk> s of the central and peripheral nervous system such as Parkinson's disease, essential tremor, amyotrophic lateral sclerosis, Tourette's syndrome, multiple sclerosis and various types of peripheral neuropathy * Sleep<unk> s such as narcolepsy * Migraines and other types of headache such as cluster headache and tension headache * Lower back and neck pain (see back pain) * Central neuropathy (see neuropathic pain) * Neuropsychiatric illnesses (diseases and/or<unk> s with psychiatric features associated with known nervous system injury, underdevelopment, biochemical, anatomical, or electrical malfunction, and/or disease pathology e.g. attention deficit hyperactivity<unk> , autism, Asperger syndrome, Tourette's syndrome and some cases of obsessive compulsive<unk>  as well as the neurobehavioral associated symptoms of degeneratives of the nervous system such as Parkinson's disease, essential tremor, Huntington's disease, Alzheimer's disease, multiple sclerosis and organic psychosis.) Many of the diseases and<unk> s listed above have neurosurgical treatments available (e.g. Tourette's syndrome, Parkinson's disease, essential tremor and obsessive compulsive<unk> . * Delirium and dementia such as Alzheimer's disease * Dizziness and vertigo * Stupor and coma * Head injury * Stroke (CVA, cerebrovascular attack) * Tumors of the nervous system (e.g. cancer) * Multiple sclerosis and other demyelinating diseases * Infections of the brain or spinal cord (including meningitis) * Prion diseases (a type of infectious agent) * Complex regional pain syndrome (a chronic pain condition)<unk> s in non-human animals are treated by veterinarians.
