Neurological disease is relatively common in snakes. Viral infections may present with neurological signs and hypothiaminosis is very common in [[Garter Snake|garter snakes]].

==Examination==
As with other problems of snakes, [[Lizard and Snake Taking a History|history-taking]] is critical for diagnosis. Signalment information can help determine the cause since many neurological diseases are more prevalent in certain taxa. [[Category:Snake Husbandry|Husbandry information]] will help to determine whether the nervous system is involved specifically or secondarily.  Clinical signs of neurological disease in snakes vary from very subtle to severe. There may be only a mild decrease in activity and a drop off in appetite. More obvious signs include disorientation, incoordination, loss of righting reflex, paresis, paralysis, head tremors, opisthotonous and convulsions.

==Diagnosis==
 
The aetiology of neurological disease can be suggested by signalment. Inclusion body disease (IBD) is almost always seen in Boidae. [[Ophidian Paramyxovirus|Ophidian paramyxovirus]] (OPMV) occurs principally in [[Viperidae]]. Hypothiaminosis is common in fish-eating snakes such as [[Garter Snake|garter snakes]].  Disorientation and sluggishness may be attributed to a wide variety of causes but may be simply caused by an inappropriate environmental temperature.  [[Snake Physical Examination|Physical examination]] may rule out cases of trauma.  The use of diagnostic aids may identify the cause: [[Lizard and Snake Imaging|radiography]] may reveal fractures, [[Lizard and Snake Haematology|haematology]] may indicate an infectious cause, and serology may identify [[Ophidian Paramyxovirus|OPMV]]. Response to thiamine is diagnostic for hypothiaminosis. However sometimes the aetiology is only found upon [[Snake Necropsy|necropsy]]. Perivascular cuffing in CNS issue may be associated with viral infections.

*'''Behavioural''' - Aggressive behaviour may be normal in some species such as [[Anaconda|anacondas]]. However, aggression in large [[Python|pythons]] has been associated with sudden changes in the [[Snake Diet|diet]]. Some large pythons also become conditioned to become aggressive by some feeding techniques.
