New hope for cluster headache sufferers
31 January 2011
Patients who suffer from severe cluster headaches are being offered new hope thanks to a revolutionary treatment at the National Hospital for Neurology and Neurosurgery (NHNN).
The pain of cluster headaches (CH) is notoriously
excruciating and usually described as one of the most distressing
conditions known to mankind. Female patients describe attacks as worse
than childbirth and patients are occasionally driven to suicide. Attacks
last between 15 minutes and three hours and can occur up to eight times
a day.
For a small group of CH patients there has been no solution. Until now.
The
treatment, known as deep brain stimulation, is already used to treat
other neurological conditions such as Parkinson’s disease and dystonia.
In CH patients, it is used to target a part of the brain (the posterior
hypothalamus) which is overactive during the headaches. An electrode is
inserted into the brain and linked to a stimulator under the chest. When
the stimulator is switched on, an electric current passes into the
brain, blocking the damaging signals that cause cluster headaches.
This
new method of treating cluster headaches follows on from pioneering
research at Queen Square, where the NHNN and the nearby Institute of
Neurology at UCL are housed.
The research, which goes back a
decade, pinpointed a particular region of the brain (the posterior
hypothalamus) and studies revealed the presence of increased blood flow
in this region during a cluster headache attack, a sure sign of
increased activity.
Early pilot results of DBS in a small number
of patients with unremitting chronic cluster headaches were very
encouraging and this led two consultants, neurologist Manjit Matharu and neurosurgeon Ludvic Zrinzo to introduce the procedure at the NHNN.
Mr
Matharu and Mr Zrinzo said: “We are really excited about the early
indications from using DBS in this way. Patients who suffer from this
excruciating condition come to us at their wits’ end and for many of
them we are a last resort. Unless you have experienced cluster headaches
you cannot underestimate the impact they have on the lives of sufferers
and their families. If we can help them in any way it’s immensely
rewarding,” they said.
