Charcot Marie Tooth disease is an inherit motor and centripetal neuropathy that affects the peripheral brass . First , permit ’s see what are peripheral mettle and this will help you understand whether it sham the brain and heart or not .
Peripheral boldness go to the peripheral neural system and these brass rest outside the brain and spinal cord and connect the central nervous system to the peripheral unquiet system . Cranial nerves , peripheral nerves , spinal boldness , and their roots and neuromuscular junctions all belong to the peripheral nervous system . There are three types of peripheral nerves : the sensory nerve which carry information regarding sensation to the brain , motor nerves which dribble boldness signal from the wit to the muscle for muscle movements and autonomic heart which innervate the unvoluntary muscleman present in the centre and glands and legato brawn cellular phone . Any injury to the peripheral nerve can make muscle weakness , loss of sentiency , abnormal sensation and autonomic disfunction . The severity depends on the degree of peripheral cheek damage.(1 ) ( 2 ) ( 3 )
Does Charcot Marie Tooth Affect The Brain?
In Charcot Marie Tooth the peripheral nerves are damaged due to mutation in dissimilar cistron that give educational activity to make proteins that are affect with the map of the peripheral nerves in the foot , leg , hands , and branch . The exact irregularity the Charcot Marie Tooth factor variation cause in these protein is clearly not known . The most likely possibility is a shift in these protein impair the nerve conduction through axons or affect the cells that produce myelin in the nerve cells . This affects the nerve conductivity of the peripheral nerves lead nerve degeneration . The nerves that are prospicient and face that transmit signal to outgrowth are affected more as the axons are longer in these nerves . Therefore , heart in the extremities are affect more than other parts of the body.(4 )
The brain is not involved in Charcot Marie Tooth , the central neural scheme is not affect by Charcot Marie Tooth therefore , there is no job in the brain office . The problem is with the peripheral nerves . The encephalon sends accurate signals to the peripheral nerves but because of their disfunction the peripheral nerves can not transmit these sign in good order to the heftiness , therefore , the muscles are not working by rights and becomes imperfect . Similarly , the sensory signals are not carried accurately to the brain so , some mass will feel a sensory loss and whereas some sensory signals will be interpreted by the brain abnormally , therefore , some multitude sense abnormal sensations too .
Does Charcot Marie Tooth Affect The Heart?
The heart affaire in Charcot Marie Tooth is not try a portion and remains controversial . There are some vitrine reports of Charcot Marie Tooth patient get fondness arrhythmias , conduction kerfuffle and dilated cardiac myopathy . The accurate chemical mechanism of how peripheral nerves cause problems in the core is unsung as the nitty-gritty muscle have their own conduction system , however , the heart is innervated by the autonomic queasy system and it is also part of the peripheral nervous system of rules . The exact mechanism is of spirit involution is not known and research studies are guide to find more about this involvement.(5 )
Conclusion
Peripheral nerve belong to the peripheral nervous system and it connects the peripheries ( muscle and sensory secretory organ ) to the central anxious organisation and channelise the signals from and to the brain from the peripheries . Charcot Marie Tooth fall out due to a cistron mutation that affects the peripheral nerves . The central flighty organization nerves are not affect by Charcot Marie Tooth . Therefore , the brain functions are not bear upon however , the wit signaling is not properly shift to the peripheries and vice versa . The heart involvement in Charcot Marie Tooth is not heard a lot and remains controversial . There are some casing reports of Charcot Marie Tooth patient feature philia arrhythmia , conductivity disturbances and dilated cardiac myopathy . The exact chemical mechanism of how peripheral nerves cause problem in the nub is unsung .
